AI中文摘要

大型语言模型在公共话语中的日益突出为民主审议带来了机遇和挑战。虽然红队策略有助于缓解特定风险,但关于语言限制、偏见和LLM的谄媚倾向等更广泛的担忧仍然存在。本章探讨如何利用LLM显著扩大和民主化审议,特别是在促进包容性和赋权传统边缘群体方面。借鉴系统功能语言学的概念,本章考察了语言使用者之间的差异(例如,关于社会人口群体)和语言使用中的差异(例如,关于交际功能)如何影响AI支持的审议参与。本章介绍了AI驱动的审议研究,并评估了它们在支撑论证、增强可及性以及减少嵌入在声望语域中的排斥性语言规范和偏见的影响方面的潜力。同时,本章警告不要过度承诺(导致不切实际的期望)和低估承诺(冒着错失AI辅助参与机会的风险)。最后,本章确定了未来的研究方向,以最大化AI辅助参与的民主潜力,同时嵌入伦理保障以抵消语言不平等的再生产。

英文摘要

The increasing prominence of Large Language Models (LLMs) in public discourse presents both opportunities and challenges for democratic deliberation. While red teaming strategies help mitigate specific risks, broader concerns persist regarding linguistic constraints, biases, and the sycophantic tendencies of LLMs. This chapter explores how LLMs can be used to significantly scale up and democratise deliberation, particularly in fostering inclusivity and empowering traditionally marginalised groups. Drawing on concepts from Systemic-Functional Linguistics, the chapter examines how variations across language users (for example, with respect to socio-demographic groups) and across language use (for example, with respect to communicative functions) shape participation in AI-supported deliberation. The chapter presents AI-driven deliberation studies and assesses their potential to scaffold argumentation, enhance access, and reduce the influence of exclusionary linguistic norms and biases which are embedded in prestigious registers. At the same time, the chapter cautions against both overclaiming, which leads to unrealistic expectations, and underclaiming, which risks missed opportunities for AI-assisted engagement. The chapter concludes by identifying future research directions to maximise the democratic potential of AI-assisted participation while embedding ethical safeguards to counteract the reproduction of linguistic inequalities.

AI中文摘要

基于概率模型的进化算法在黑箱优化中很有前景。具体来说,自适应随机自然梯度(ASNG)自适应地更新其学习率(概率模型进化算法中的典型超参数),从而实现高效且鲁棒的优化。尽管权重参数是常见的超参数,但随着对耗时任务并行评估需求的增加,如何为更大的种群规模设置合适的权重仍不清楚。在本文中,我们提出了权重自适应ASNG(WA-ASNG),它将权重自适应机制融入ASNG。我们从自然梯度的累积中计算更新方向的估计信号。然后,为了最大化该信号,WA-ASNG通过优化上的梯度上升自适应地更新其权重参数。学习率自适应在满足预期目标值单调改进的充分条件方面发挥作用,而权重自适应机制旨在最大化这种改进。实验结果表明,在二进制优化问题中,种群规模从25到100的各种设置下,WA-ASNG优于PBIL和ASNG。此外,WA-ASNG在存在强噪声的情况下也能高效运行。我们的代码可在此https URL获取。

英文摘要

Probabilistic model-based evolutionary algorithms are promising for black-box optimization. Specifically, the adaptive stochastic natural gradient (ASNG) adaptively updates its learning rate, a typical hyperparameter in probabilistic model-based evolutionary algorithms, thereby realizing efficient and robust optimization. Although weight parameters are common hyperparameters, with the increasing demand for parallel evaluation of time-consuming tasks, it remains unclear how to set suitable weights for larger population sizes. In this paper, we propose Weight Adaptation ASNG (WA-ASNG), which incorporates a weight adaptation mechanism into ASNG. We calculated the estimated signal of the update direction from the accumulations of the natural gradient. Then, to maximize the signal, WA-ASNG adaptively updates its weight parameters by a gradient ascent over the optimization. While the learning rate adaptation plays a role in satisfying a sufficient condition for monotonic improvement of the expected objective value, the mechanism of weight adaptation is intended to maximize this improvement. The experimental results demonstrate that WA-ASNG outperforms PBIL and ASNG across various settings with population sizes ranging from 25 to 100 for binary optimization problems. Furthermore, WA-ASNG can perform efficiently in the presence of strong noise. Our code is available at https://github.com/shiralab/WA-ASNG .

AI中文摘要

大型语言模型(LLM)通常使用人类可读的自然语言进行提示和交互,即使目标读者是另一个模型。本文研究语义信息是否可以编码为紧凑、非标准的文本形式,这种形式牺牲了人类可读性,但能被LLM恢复。我们将这类以模型为中心的文本表示称为BabelTele,这里不是作为固定协议,而是作为探索LLM生成和解释此类表示能力的经验探针。通过可读性诊断、模型似然度量、人类问卷和下游任务评估,我们发现BabelTele可以显著偏离普通自然语言,同时为指令调优的LLM保留核心语义。作为一种任务无关的表示范式,BabelTele展示了高信息密度,即使文本体积压缩到原始长度的27.9%,也能保持99.5%的语义保真度。我们进一步评估了其在跨模型迁移、智能体记忆和多智能体通信中的语义鲁棒性。结果表明,BabelTele可以降低上下文开销,同时通常保持可靠的下游性能,但其有效性取决于压缩器-读取器对和任务设置。这些发现表明,人类可读性、自然语言典型性和模型端语义可恢复性可以部分解耦,为未来探索LLM系统中的模型原生表示开辟了道路。

英文摘要

Large language models (LLMs) are commonly prompted and interfaced with human-readable natural language, even when the intended reader is another model. This paper investigates whether semantic information can be encoded in compact, non-standard textual forms that sacrifice human readability while remaining recoverable by LLMs. We refer to this class of model-centric textual representations as BabelTele, approached here not as a fixed protocol but as an empirical probe into LLMs' capacity to generate and interpret such representations. Through readability diagnostics, model likelihood measures, human questionnaires, and downstream task evaluations, we find that BabelTele can substantially depart from ordinary natural language while preserving core semantics for instruction-tuned LLMs. As a task-agnostic representational paradigm, BabelTele demonstrates high information density, maintaining 99.5% semantic fidelity even when the text volume is condensed to 27.9% of its original length. We further evaluate its semantic robustness in cross-model transfer, agent memory, and multi-agent communication. Results suggest that BabelTele can reduce context overhead while generally maintaining reliable downstream performance, although its effectiveness depends on the compressor-reader pair and task setting. These findings indicate that human readability, natural-language typicality, and model-side semantic recoverability can be partially decoupled, opening a path toward model-native representations in future exploration of LLM systems.

从病理报告中提取信息对于癌症分期和肿瘤登记人群至关重要。然而关键数据仍嵌入在叙述性报告中,使得手动提取劳动密集且易出错。传统的监督自然语言处理流程通过完全监督的命名实体识别和关系提取来解决这一问题,但需要昂贵的人工标注,并且当上游实体缺失时会出现级联故障。在本研究中,我们开发了一个零样本智能体工作流,并评估了五个开源生成式大语言模型(LLMs),以从肺切除病理报告中填充13个美国病理学家学会的概要字段。我们使用一种新颖的、与注册对齐的评估框架,将它们与最先进的监督GatorTron NER-RE基线进行比较。基线达到了0.960的Micro-F1,而最佳零样本模型(GPT-OSS-20B)达到了0.893的Micro-F1(召回率:0.949),在没有任务特定训练的情况下准确提取了复杂关系(如病理分期)。这些结果表明,开源零样本智能体LLMs是提取肺部病理信息的低成本解决方案。

英文摘要

Information extraction from pathology reports is essential for cancer staging, tumor registry population. Yet key data remains embedded in narrative reports, making manual extraction labor-intensive and error-prone. Traditional supervised Natural Language Processing pipelines address this through fully supervised Named Entity Recognition and Relation Extraction, but require expensive manual annotation and suffer cascading failures when upstream entities are missed. In this study, we developed a zero-shot, agentic workflow, and evaluated five open-source generative Large Language Models (LLMs) to populate 13 College of American Pathologists synoptic fields from lung resection pathology reports. We compared them against a state-of-the-art supervised GatorTron NER-RE baseline using a novel, registry-aligned evaluation framework. The baseline achieved Micro-F1of 0.960, while the best zero-shot model (GPT-OSS-20B) achieved Micro-F1 of 0.893 (recall: 0.949), accurately extracting complex relations like Pathologic Stage without task-specific training. These results suggest that open-source, zero-shot agentic LLMs are a low-cost solution for extracting lung pathology information.

AI中文摘要

深度神经网络(DNN)在各个领域表现出色,但通常可解释性较低。神经加性模型(NAM)及其变体神经基础模型(NBM)在广义加性模型(GAM)中使用神经网络(NN)作为非线性形状函数。这两种模型具有高度可解释性,并且在NN训练中表现出良好的性能和灵活性。NAM和NBM基于GAM架构,可以提供并可视化每个特征对预测的贡献。然而,当使用双输入NN来考虑特征交互或将其应用于高维数据集时,由于所需计算资源的增加,训练NAM和NBM变得棘手。本文提出将特征选择机制融入NAM和NBM以解决计算瓶颈。我们在两种模型中引入特征选择层,并在训练过程中更新选择权重。我们的方法简单,与原始NAM和NBM相比,可以降低计算成本和模型大小。此外,它使我们即使在数据维度很高的情况下也能使用双输入NN并捕获特征交互。我们证明,所提出的模型与原始NAM和NBM相比计算效率更高,并且与最先进的GAM相比表现出更好或相当的性能。

英文摘要

Deep neural networks (DNNs) exhibit attractive performance in various fields but often suffer from low interpretability. The neural additive model (NAM) and its variant called the neural basis model (NBM) use neural networks (NNs) as nonlinear shape functions in generalized additive models (GAMs). Both models are highly interpretable and exhibit good performance and flexibility for NN training. NAM and NBM can provide and visualize the contribution of each feature to the prediction owing to GAM-based architectures. However, when using two-input NNs to consider feature interactions or when applying them to high-dimensional datasets, training NAM and NBM becomes intractable due to the increase in the computational resources required. This paper proposes incorporating the feature selection mechanism into NAM and NBM to resolve computational bottlenecks. We introduce the feature selection layer in both models and update the selection weights during training. Our method is simple and can reduce computational costs and model sizes compared to vanilla NAM and NBM. In addition, it enables us to use two-input NNs even in high-dimensional datasets and capture feature interactions. We demonstrate that the proposed models are computationally efficient compared to vanilla NAM and NBM, and they exhibit better or comparable performance with state-of-the-art GAMs.

AI中文摘要

流式视频大模型必须持续处理传入的视频,同时保持低查询延迟,这使得视频摄入吞吐量和查询时间响应性对于实时部署至关重要。现有方法主要集中于加速单个模块,如视觉编码、令牌剪枝或KV缓存压缩,但对由此产生的系统能否维持实时流式性能提供的见解有限。我们将流式视频大模型推理形式化为一个协调的流水线,涵盖视觉预处理、视觉编码、令牌丢弃和LLM预填充/解码。基于这一形式化,我们提出了ViCoStream(视频协调流式处理),一个阶段协调的流式框架,结合了分块执行、CUDA流重叠、视觉令牌控制、有界视觉注意力和查询端检索,以限制每块的计算和内存成本。我们进一步对瓶颈迁移进行了系统研究,揭示了块大小、令牌保留、注意力局部性和检索范围如何影响吞吐量-准确率权衡。在多个流式基准测试上使用Qwen2.5-VL-3B/7B-Instruct进行的实验表明,ViCoStream在单块A100 GPU上实现了134 FPS的视频吞吐量和小于50 ms的首令牌延迟,同时保持接近全历史基线的准确率。

英文摘要

Streaming VideoLLMs must continuously process incoming video while maintaining low query latency, making both video-ingestion throughput and query-time responsiveness critical for real-time deployment. Existing methods largely focus on accelerating individual modules, such as visual encoding, token pruning, or KV-cache compression, but provide limited insight into whether the resulting system can sustain real-time streaming performance. We formulate streaming VideoLLM inference as a coordinated pipeline spanning visual preprocessing, visual encoding, token dropping, and LLM prefilling/decoding. Building on this formulation, we propose ViCoStream (Video Coordinated Streaming), a stage-wise coordinated streaming framework that combines chunk-wise execution, CUDA-stream overlap, visual token control, bounded visual attention, and query-side retrieval to bound per-chunk computation and memory costs. We further provide a systematic study of bottleneck migration, revealing how chunk size, token retention, attention locality, and retrieval scope shape the throughput-accuracy trade-off. Experiments with Qwen2.5-VL-3B/7B-Instruct across multiple streaming benchmarks show that ViCoStream achieves 134 FPS video throughput and less than 50 ms TTFT on a single A100 GPU while maintaining accuracy close to full-history baselines.

AI中文摘要

大型语言模型(LLM)展示了强大的推理和生成能力,但其固定的上下文窗口限制了跨多会话交互的长期信息积累和重用。现有的记忆增强系统通常以粗粒度且不稳定的方式构建记忆,依赖于低效的记忆表示或不稳定的无约束更新。为了解决这些挑战,我们提出了AtomMem,一种专为价值密集存储和稳定记忆演化设计的长期记忆系统。AtomMem引入了一个事实执行器,从长形式交互中选择性地提取高价值原子事实,作为高效的记忆表示。随后,AtomMem将这些事实组织成层次化的事件结构和时间档案,捕获连贯的情景上下文并随时间跟踪动态演变的用户属性。在检索过程中,系统激活一个关联记忆图来连接碎片化的记忆。在LoCoMo基准上的实验证实,AtomMem在各种推理任务中实现了最先进的性能,为部署智能个性化智能体提供了一种可扩展且经济可行的解决方案。

英文摘要

Large language models (LLMs) demonstrate strong reasoning and generation abilities, but their fixed context windows limit long-term information accumulation and reuse across multi-session interactions. Existing memory-augmented systems often construct memory in a coarse and unstable manner, relying on inefficient memory representations or unstable unconstrained updates. To address these challenges, we propose AtomMem, a long-term memory system designed for value-dense storage and stable memory evolution. AtomMem introduces a Fact Executor, which selectively extracts high value atomic facts from long form interactions to serve as highly efficient memory representations. Subsequently, AtomMem organizes these facts into hierarchical event structures and temporal profiles, capturing coherent episodic contexts and tracking dynamically evolving user attributes over time. During retrieval, the system activates an associative memory graph to connect fragmented memories. Experiments on the LoCoMo benchmark confirm that AtomMem achieves state-of-the-art performance across various reasoning tasks, offering a scalable and economically viable solution for deploying intelligent personalized agents.

AI中文摘要

多视图成像(如乳腺X线摄影和胸部X线摄影)是临床实践的标准组成部分。然而,医学图像通常未配准,且包含视图特定的伪影或无关背景线索,这些可能掩盖诊断相关发现。许多现有方法直接融合每个视图的表征,使得此类无关内容污染融合嵌入,并在不同视图配置下降低鲁棒性。我们提出OTCHA,一种基于最优传输(OT)的置信度感知潜在中心令牌对齐模块,在融合前细化补丁令牌以用于多视图分类。OTCHA引入一组跨视图共享的可学习潜在中心令牌。对于每个视图,我们计算补丁令牌与中心令牌之间的OT计划,该计划联合考虑特征相似性和几何结构,并通过令牌条件尘埃箱增强OT公式以实现部分匹配并丢弃无关令牌。所得传输计划提供令牌级匹配置信度,该置信度门控中心介导的消息传递,并加权一种新的基于最优传输的表征对齐损失以稳定细化。在三个多视图医学图像数据集上的实验表明,在不同解剖结构和视图配置下,相比竞争基线方法取得一致改进。我们的代码可在该https URL获取。

英文摘要

Multi-view imaging, such as mammography and chest radiography, is a standard component of clinical practice. However, medical images are often unregistered and contain view-specific artifacts or irrelevant background cues that can obscure diagnostically relevant findings. Many existing methods directly fuse per-view representations, allowing such irrelevant content to contaminate the fused embedding and reducing robustness under varying view configurations. We propose OTCHA, a confidence-aware latent hub token alignment module based on optimal transport (OT) that refines patch tokens before fusion for multi-view classification. OTCHA introduces a set of learnable latent hub tokens shared across views. For each view, we compute an OT plan between patch tokens and hub tokens that jointly considers feature similarity and geometry, and augment the OT formulation with token-conditional dustbins to enable partial matching and discard irrelevant tokens. The resulting transport plan provides token-wise matching confidence, which gates hub-mediated message passing and weights a novel optimal-transport-based representation alignment loss to stabilize refinement. Experiments on three multi-view medical image datasets demonstrate consistent improvements over competing baselines across diverse anatomies and view configurations. Our code is available at https://github.com/labhai/OTCHA.

自动驾驶车辆必须在现实世界中安全运行,而错误可能带来严重后果。尽管现代端到端驾驶策略在常规场景中表现出色,但其可靠性受限于真实驾驶数据集中安全关键的“长尾”事件的稀缺性。这些罕见交互定义了学习策略的实际安全边界,但在现实世界中难以大规模收集。我们展示了这一根本限制可以通过在合成的关键交互上对预训练驾驶模型进行后训练来解决。我们引入了World Engine,一个生成式框架,从真实日志中重建高保真交互环境,并系统性地将其外推为现实的安全关键变体。这一范式使得基于强化的后训练能够将策略与安全约束对齐,规避现实世界探索中固有的物理风险。在基于nuPlan构建的公开基准上,World Engine显著减少了罕见安全关键场景中的故障,并且相比仅扩展预训练数据带来了更大的增益。此外,当部署到生产级自动驾驶系统时,所得策略减少了模拟碰撞,并在道路测试中显示出可衡量的改进,表明在合成的安全关键交互上进行后训练为更安全的自动驾驶提供了一条可扩展且有效的途径。完整的代码库套件(包括训练)已向公众发布。

英文摘要

Autonomous vehicles must operate safely in the real world, where errors can have severe consequences. Although modern end-to-end driving policies excel in routine scenarios, their reliability is limited by the scarcity of safety-critical ``long-tail'' events in real driving datasets. These rare interactions define the practical safety boundary of the learned policy, yet they are difficult to collect at scale in the real world. Here we show that this fundamental limitation can be addressed by post-training pre-trained driving models on synthesized high-stakes interactions. We introduce World Engine, a generative framework that reconstructs high-fidelity interactive environments from real-world logs and systematically extrapolates them into realistic safety-critical variations. This paradigm enables reinforcement-based post-training to align policies with safety constraints, circumventing the physical risks inherent in real-world exploration. On a public benchmark built on nuPlan, World Engine substantially reduces failures in rare safety-critical scenarios and yields significantly larger gains than scaling pre-training data alone. Furthermore, when deployed on a production-scale autonomous driving system, the resulting policy reduces simulated collisions and demonstrates measurable improvements in on-road testing, showing that post-training on synthesized, safety-critical interactions offers a scalable and effective pathway to safer autonomous driving. The full codebase suite, including training, is released to the public.

事件相机通过将动态场景表示为微秒分辨率的连续事件流,以卓越的时间保真度捕捉动态场景。然而,每个单独的事件仅携带最小的语义价值,仅仅表示局部亮度变化。为了获得有意义的信号,下游算法需要快速整合来自潜在大量低信息事件流的线索。然而,当前的架构很容易被淹没,难以在捕捉细粒度时间动态和维持可管理的数据吞吐量之间取得平衡。本文提出一个框架,将事件流重新标记为少量高信息量的“神经事件”,每个事件代表一个局部时空上下文窗口,并带有离散可学习编码。每次该编码翻转时,触发一个神经事件,产生高度压缩的数据流。我们证明,在物体检测和分类任务中,基于神经事件训练的网络与最先进方法性能相当或更优,同时将事件率降低2.0倍。

英文摘要

Event cameras capture dynamic scenes with exceptional temporal fidelity by representing them as a continuous stream of microsecond resolution \textit{events}. Each individual event, however, only carries minimal semantic value, merely signaling a localized brightness change. To derive meaningful signals, downstream algorithms need to quickly integrate cues from a potentially massive torrent of low-information events. Current architectures, however, are easily overwhelmed, struggling to balance capturing fine-grained temporal dynamics and maintaining a manageable data throughput. This paper proposes a framework to re-tokenize event streams into a small set of highly informative \textit{neural events}, each representing a local spatio-temporal context window with a discrete learnable code. Every time this code flips, a neural event is triggered, yielding a highly compressed data stream. We demonstrate that, across object detection and classification, networks trained on neural events are on par or surpass the performance of state-of-the-art approaches while reducing the event rate by a factor of 2.0.

AI中文摘要

对齐语言模型通过稀疏前馈神经元门控拒绝和语言路由等行为,但尚无理论预测单神经元干预何时连贯地控制行为而非导致输出崩溃。我们开发了一个预算归一化的控制窗口框架用于单神经元操控。沿一个写入方向的剂量简化为一个控制坐标:残差流与写入之间的对齐,该对齐沿着一条通用饱和曲线驱动,以残差范数除以写入范数设定的相干预算为单位。当行为触发点低于崩溃上限时,存在连贯控制。同一坐标控制良性模式切换和拒绝;上限由权重和一次通用前向传播得出,而触发点在 rollout 时测量。在15个保留神经元上,预测上限的平均绝对误差为0.14,在批量层中约为0.07,并且承诺的开启或关闭判定在11个神经元上成立,而多数基线为10/15。关闭情况揭示了三种失败模式而非违反:触发前崩溃、深度不足以传播、或归一化限制了单个神经元能推动的距离。该定律解释了为什么局部梯度归因反直觉地预测控制:真正的控制器偏离读出轴写入,并携带接近零的一阶梯度。由窗口精确化的仅前向对比筛选恢复了归因遗漏的控制器。在拒绝这一最难案例中,干预成功是类型化的而非标量:连贯旁路和严格可操作可达性分离,因此一个神经元可以在流畅、任务相关且无操作内容的文本中翻转拒绝,而真正的可操作可达性仅出现在六个审计的 Llama 枢轴中的三个,且仅在较晚的 rollout 时间范围内。因此,单神经元操控是对可控性的预算化、类型化审计,而非固定剂量的轶事。

英文摘要

Aligned language models gate behaviors such as refusal and language routing through sparse feed forward neurons, yet no theory predicts when a single neuron intervention controls a behavior coherently rather than collapsing the output. We develop a budget normalized control window framework for single neuron steering. A dose along one write direction reduces to one control coordinate: the alignment between the residual stream and the write, driven along a universal saturation curve in units of a coherence budget set by the residual norm divided by the write norm. Coherent control exists when a behavior trigger lies below the collapse ceiling. The same coordinate governs benign mode switches and refusal; the ceiling follows from weights and one generic forward pass, while triggers are measured at rollout. On fifteen held out neurons, the predicted ceiling has mean absolute error 0.14, about 0.07 in bulk layers, and the committed open or closed verdict holds on eleven against a ten of fifteen majority baseline. Closed cases expose three failure modes rather than violations: collapse before trigger, too little depth to propagate, or a normalization that caps how far one neuron can push. The law explains why local gradient attribution anti predicts control: true controllers write off the readout axis and carry a near zero first order gradient. A forward only contrastive screen made precise by the window recovers controllers that attribution misses. On refusal, the hardest case, intervention success is typed, not scalar: coherent bypass and strict actionable reach separate, so a neuron can flip refusal in fluent, on task text with no actionable content, and genuine actionable reach appears only for three of six audited Llama pivots and only at later rollout horizons. Single neuron steering is therefore a budgeted, typed audit of controllability rather than a fixed dose anecdote.

AI中文摘要

当前AI驱动的游戏开发在资产生成、游戏设计和基于Web的游戏编码方面取得了实质性进展,但由于缺乏大规模数据集和确定性评估方法,专业游戏引擎上的项目级代码工程仍然很大程度上未被探索。我们提出了JamSet和JamBench,这是首个基于专业游戏引擎的项目级游戏代码框架数据集和基准。我们的关键洞察是,Game Jam竞赛(开发者在严格时间限制下构建完整游戏的社区活动)产生了数千个适合此目的的开源项目。基于Godot引擎的文本格式和无头执行模式,我们设计了一个从文件完整性到运行时行为收集的确定性验证流程,从超过24万个仓库中提炼出8133个已验证项目。其中,300个手动验证的项目构成JamBench;其余构成JamSet。JamBench定义了主题驱动的生成和代码补全任务,通过结合编译通过率、结构完整性得分(SCS)和行为对齐得分(BAS)的流水线进行评估。对9个前沿模型的评估揭示了随着项目规模增加的能力悬崖,运行时通过率从小型项目的80.4%下降到大型项目的5.7%(Task2a)。代码代理提高了编译率,但在运行时行为质量上没有带来提升,表明瓶颈在于架构设计而非语法正确性。实验验证了JamSet作为有效训练数据。所有数据和代码均已公开。

英文摘要

Current AI-driven game development has made substantial progress in asset generation, gameplay design, and web-based game coding, yet project-level code engineering on professional game engines remains largely unexplored due to the absence of large-scale datasets and deterministic evaluation methods. We present JamSet and JamBench, the first project-level game code framework dataset and benchmark built on a professional game engine. Our key insight is that Game Jam competitions, community events where developers build complete games under tight time constraints, yield thousands of open-source projects suitable for this purpose. Building on the Godot engine's text-based format and headless execution mode, we design a deterministic verification pipeline from file integrity to runtime behavior collection, distilling 8,133 verified projects from over 240,000 repositories. Of these, 300 manually verified projects form JamBench; the rest constitute JamSet. JamBench defines theme-driven generation and code completion tasks, evaluated through a pipeline combining compilation pass rates, Structural Completeness Score (SCS), and Behavioral Alignment Score (BAS). Evaluation of 9 frontier models reveals a capability cliff as project scale increases, with runtime pass rates dropping from 80.4% on small projects to 5.7% on large ones (Task2a). Code Agents improve compilation rates yet yield no gains in runtime behavioral quality, indicating that the bottleneck lies in architectural design rather than syntactic correctness. Experiments validate JamSet as effective training data. All data and code are publicly available.

3D-PLOT-LLM: Part-Level Object Tokens for 3D Large Language Models

3D-PLOT-LLM: 用于三维大语言模型的部件级对象标记

AI总结 提出3D-PLOT-LLM,通过重组输入标记流使部件可直接通过LLM词汇寻址,无需分割解码器或边界框,在部件级基准上超越现有方法。

详情
AI中文摘要

三维多模态大语言模型(3D MLLMs)将3D对象作为一个整体进行描述,但无法处理、命名或推理其部件。先前的部件感知尝试增加了分割解码器、更重的3D编码器或边界框语法,导致参数成本大幅增加。我们采取了一条根本不同的路径:重新组织输入标记流,使得部件通过LLM自身的词汇变得可直接寻址。我们的模型3D-PLOT-LLM将冻结的点编码器的块分割成K个局部一致的区域,并在每个区域的块标记之前插入一个可学习的每区域标记和一个保留词汇标记<part_k>;然后,一个标记空间精化(MSR)模块根据每个区域的空间统计信息和邻接邻居对该标记进行条件化。因此,模型在其输出中引用部件,并遵循通过标记引用部件的提示,这是先前对象级3D MLLMs所不具备的能力。为了探究这一接口,我们构建了PartVerse-QA,一个基于PartVerse网格注释改编的词汇级部件问答基准(77K训练对和588个保留查询,基于不相交的对象划分),在该基准上,3D-PLOT-LLM达到了描述到槽的Jaccard指数0.459和精确匹配率13.78%,槽到描述的GPT-4o评判得分为44.68。在3DCoMPaT-GrIn部件感知接地描述基准上,3D-PLOT-LLM在所有文本输出指标上优于PointLLM、Kestrel、PARIS3D和SegPoint,并在4项指标中的3项上优于ShapeLLM,相比PointLLM的GPT-4o评判得分最高提升+3.03。在Objaverse整体对象描述中,在第二阶段添加PartVerse-QA使得相比PointLLM的SBERT得分提升+0.65,GPT-4o得分提升+1.85,并且在5项传统指标中的4项(SBERT、SimCSE、BLEU-1、METEOR)上超过PointLLM-PiSA,尽管其目标是不同的(部件接地)目标。所有这些仅需在冻结的点编码器上增加不到100万个可训练参数,比先前的部件感知3D MLLMs低一个数量级,且无需分割解码器或边界框头。

英文摘要

3D multimodal large language models (3D MLLMs) describe a 3D object as a whole but cannot address, name, or reason about its parts. Prior part-aware attempts add segmentation decoders, heavier 3D encoders, or bounding-box grammars at substantial parameter cost. We take a fundamentally different path: we reorganize the input token stream so that parts become directly addressable through the LLM's own vocabulary. Our model, 3D-PLOT-LLM, partitions the frozen point encoder's patches into K locally coherent regions and inserts, before each region's patch tokens, a learnable per-region marker and a reserved vocabulary token <part_k>; a Marker-Space Refinement (MSR) module then conditions each marker on its region's spatial statistics and adjacency neighbors. The model thus cites parts in its output and follows prompts that refer to parts by token, a capability absent from prior object-level 3D MLLMs. To probe this interface, we construct PartVerse-QA, a vocabulary-level part-QA benchmark adapted from PartVerse mesh annotations (77K training pairs and 588 held-out queries on disjoint object splits), on which 3D-PLOT-LLM reaches caption-to-slots Jaccard 0.459 and Exact-match 13.78%, with a slot-to-caption GPT-4o judge of 44.68. On the 3DCoMPaT-GrIn part-aware grounded description benchmark, 3D-PLOT-LLM outperforms PointLLM, Kestrel, PARIS3D, and SegPoint on every text-output metric, and ShapeLLM on 3 of 4, with up to +3.03 GPT-4o judge over PointLLM. On Objaverse whole-object captioning, adding PartVerse-QA at Stage 2 yields +0.65 SBERT and +1.85 GPT-4o over PointLLM, and tops PointLLM-PiSA on 4 of 5 traditional metrics (SBERT, SimCSE, BLEU-1, METEOR) despite targeting a different (part-grounded) objective. All with under 1M new trainable parameters on a frozen point encoder, an order of magnitude below prior part-aware 3D MLLMs, and no segmentation decoder or bounding-box head.

AI中文摘要

医疗表格数据在临床研究中无处不在,但表格数据的深度学习仍未被充分探索,因为可靠的标签通常需要昂贵的专家判定,尽管结构化临床变量通常以表格形式常规可用。自监督学习可以利用这些未标记的表格,而最近基于分箱的前置任务提供了一种有前景的归纳偏置,但现有目标固定单个全局分位数离散化并应用特征无关的监督。我们提出自适应分箱,一种用于表格自监督学习的训练自适应离散化前置任务,通过特征级粗到细课程将离散化与学习耦合。受神经网络的频谱偏差和课程学习原则的启发,我们的方法在检测到平台期时逐步细化每个特征的离散化,并选择表示感知的分割点,以联合改善值空间浓度和表示空间一致性。一种异质性感知目标统一了类别重建与数值特征的顺序监督,在统一评估协议下对公共医疗表格数据集的实验显示,线性探测和微调均取得一致改进,无需数据集特定的离散化调整。我们进一步引入一个医疗表格自监督学习基准,配备标准化协议,以支持这一未被充分探索领域的可重复进展。我们的代码可在该网址获取。

英文摘要

Medical tabular data are ubiquitous in clinical research, but deep learning for tables remains underexplored because reliable labels often require costly expert adjudication, even though structured clinical variables are routinely available in tabular form. Self-supervised learning can leverage these unlabeled tables, and recent binning-based pretexts offer a promising inductive bias, but existing objectives fix a single global quantile discretization and apply feature-agnostic supervision. We propose Adaptive Binning, a training-adaptive discretization pretext for tabular SSL that couples discretization to learning through a feature-wise coarse-to-fine curriculum. Motivated by the spectral bias of neural networks and the principles of curriculum learning, our method progressively refines discretization per feature upon plateau detection and selects representation-aware splits to jointly improve value-space concentration and representation-space coherence. A heterogeneity-aware objective unifies categorical reconstruction with ordinal supervision for numerical features, and experiments on public medical tabular datasets under unified evaluation protocols show consistent gains for linear probing and fine-tuning without dataset-specific discretization tuning. We further introduce a medical tabular SSL benchmark with standardized protocols to support reproducible progress in this underexplored domain. Our code is available at https://github.com/labhai/Adaptive-Binning.

Heterogeneous LLM Debate Under Adversarial Peers: Honest Gains, Replacement Costs, and Resilience

对抗性同伴下的异构LLM辩论:诚实增益、替代成本与韧性

Prashanti Nilayam, Kiran Kumar Ramanna, Prashil Tumbade, Sankalp Nayak

AI总结 研究异构LLM辩论中诚实与对抗性同伴对修正行为的影响,发现诚实同伴降低有害修正率,对抗性同伴则逆转,且异构性在已有对手时也能作为防御。

详情
AI中文摘要

异构LLM辩论的动机在于,多样化的同伴可以相互纠正,但同样的交流既携带纠正也携带对抗性影响。我们通过跟踪异构同伴如何改变诚实智能体的修正行为来衡量哪种影响占主导:他们改变答案的频率,以及这种改变是纠正性的还是有害的。我们比较了匹配面板(同质基线、诚实混合和对抗混合)以及受污染面板(其中已存在一个恶意的同族同伴),涵盖四个模型家族和三个推理基准。一个诚实的异构同伴显著降低了有害修正,而对抗性同伴则逆转了这一效果。对于Llama-3.1-70B防御者在MATH-hard上,诚实插槽的有害修正率从同质面板的89%下降到有诚实同伴时的35%,而对抗性同伴使其回到90%。条件率对弱防御者隐藏了这种损害,但辩论结束时的翻转率暴露了它。该模式在家族和基准上保持符号一致,而其幅度随防御者-基准机制变化。我们还测量了当已存在一个对抗性同族同伴时的效果:一个诚实的异构同伴降低了有害修正率以及最初正确答案丢失的比率。在相同的Llama-3.1-70B设置下,添加的诚实同伴将最初正确项上的翻转率从同族对手下的31%降至6%。因此,异构性不仅是一个攻击面,而且当对手已经存在时,也是一种防御。

英文摘要

Heterogeneous LLM debate is motivated by the promise that diverse peers correct one another, but the same exchange that carries correction also carries adversarial influence. We measure which dominates by tracking how a heterogeneous peer changes the honest agents' revision behavior: how often they change their answer, and whether the change is corrective or harmful. We compare matched panels (homogeneous baseline, honest-mixed, and adversarial-mixed) and contaminated panels in which a malicious same-family peer is already present, spanning four model families and three reasoning benchmarks. An honest heterogeneous peer sharply lowers harmful revision, and an adversarial one reverses it. For Llama-3.1-70B defenders on MATH-hard, the honest-slot harmful-revision rate falls from 89% in the homogeneous panel to 35% with an honest peer, and an adversarial peer returns it to 90%. The conditional rate hides this damage on weak defenders, but the end-of-debate flip rate exposes it. The pattern keeps its sign across families and benchmarks while its magnitude varies with the defender-benchmark regime. We also measure the effects when an adversarial same-family peer is already present: an honest heterogeneous peer lowers both harmful revision and the rate at which initially-correct answers are lost. On the same Llama-3.1-70B setting, the added honest peer cuts the flip rate on initially-correct items from 31% under a same-family adversary to 6%. Heterogeneity is therefore not only an attack surface but, when an adversary is already present, also a defense.

AI中文摘要

准确预测沙尘源排放对于减轻沙尘暴带来的重大环境和健康危害至关重要。传统预测方法通常难以捕捉这些现象的复杂时空动态。在本文中,我们证明邻近图使图神经网络(GNN)能够有效建模数据点之间复杂的空间和时间关系。具体来说,我们使用邻近图——如Delaunay三角剖分、Gabriel图、k-最近邻图和Yao图——作为GNN(包括GraphSAGE、图卷积网络和图注意力网络)的输入来执行消息传递。我们的方法强调了将邻近图与GNN集成用于稳健准确的沙尘源预测的有效性。为了强调邻近图表示的重要性,我们将我们的方法与使用随机图进行消息传递的GNN进行了比较。结果表明,使用邻近图的GNN显著优于使用随机图的GNN,并且在沙尘源排放预测中也远优于长短期记忆(LSTM)模型。

英文摘要

Accurate prediction of dust source emissions is critical for mitigating the significant environmental and health hazards posed by dust storms. Traditional forecasting methods often struggle to capture the complex spatiotemporal dynamics of these phenomena. In this paper, we demonstrate that proximity graphs enable Graph Neural Networks (GNNs) to effectively model the intricate spatial and temporal relationships between data points. Specifically, we use proximity graphs--such as Delaunay triangulation, Gabriel graph, k-Nearest Neighbor graph, and Yao graph--as the input for GNNs (including GraphSAGE, Graph Convolutional Networks, and Graph Attention Networks) to perform message passing. Our approach highlights the effectiveness of integrating proximity graphs with GNNs for robust and accurate dust source forecasting. To emphasize the importance of proximity graph representations, we compare our method against GNNs using random graphs for message passing. The results show that GNNs with proximity graphs significantly outperform those with random graphs and are also far superior to Long Short-Term Memory (LSTM) model in dust source emission forecasting.

AI中文摘要

准确分割薄而曲折的解剖结构,如视网膜血管、脑血管和面部皱纹,由于低对比度、频繁断裂和严重的类别不平衡仍然具有挑战性。尽管最近的卷积和基于Transformer的模型提高了性能,但它们常常产生碎片化的预测,并且无法恢复细小的分支。我们提出了CSWinUNETR,一个用于2D和3D薄结构分割的通用骨干网络。它采用交叉形条带自注意力来建模长距离主轴上下文,并结合循环移位以增强条带间的信息交换。为了更好地保留细粒度细节,我们进一步引入了一个细节增强的多尺度自注意力模块,该模块从多分辨率表示中聚合上下文特征。此外,我们提出了稀疏控制动态蛇形卷积,它从稀疏预测的控制点重建可靠的密集曲线核,以更好地跟随曲折的几何形状。在眼科、神经血管成像和皮肤科的四个基准上的大量实验表明,CSWinUNETR在没有任务特定后处理或拓扑感知损失的情况下,始终优于最先进的方法。代码可在该网址获取。

英文摘要

Accurate segmentation of thin, tortuous anatomical structures, such as retinal vessels, cerebral vasculature, and facial wrinkles, remains challenging due to low contrast, frequent discontinuities, and severe class imbalance. Although recent convolutional and Transformer-based models have improved performance, they often yield fragmented predictions and fail to recover fine branches. We propose CSWinUNETR, a general-purpose backbone for 2D and 3D thin-structure segmentation. It employs cross-shaped stripe self-attention to model long-range principal-axis context and incorporates cyclic shifts to enhance information exchange across stripes. To better preserve fine-grained details, we further introduce a detail-enhanced multi-scale self-attention module that aggregates contextual features from multi-resolution representations. In addition, we propose sparse-control dynamic snake convolution, which reconstructs reliable dense curvilinear kernels from sparsely predicted control points to better follow tortuous geometry. Extensive experiments on four benchmarks across ophthalmology, neurovascular imaging, and dermatology demonstrate that CSWinUNETR consistently outperforms state-of-the-art methods without task-specific post-processing or topology-aware losses. The code is available at https://github.com/labhai/CSWinUNETR.

We present the AL*RTA algorithm for learning alternating real-time automata (ARTAs) using membership and equivalence queries. AL*RTA combines ideas from AL*for learning alternating finite automata and NL*RTA for learning nondeterministic real-time automata. We first define ARTAs and show that alternation improves succinctness, although it does not increase expressive power. We then present AL*RTA and show its termination. Our empirical evaluation suggests that AL*RTA generally learns smaller automata than NL*RTA at the cost of more queries.

AI中文摘要

关键性能测量(KPM)预测对于5G及下一代电信网络的主动网络管理至关重要。然而,现有的机器学习(ML)方法在可扩展性和可解释性方面存在显著局限性,限制了其在实际部署中的有效性。我们提出TelcoAgent,一个基于基础模型的框架,能够在不需站点特定训练的情况下,跨不同网络单元实现多个KPM的准确、可扩展和可解释预测。具体而言,该框架包含三个关键组件:(i) 一个自动化的三智能体管道,直接从规范文档构建第三代合作伙伴计划(3GPP)知识图谱;(ii) 一个可扩展的基于时间序列基础模型(TSFM)的预测管道,以提供准确的零样本预测;以及(iii) 一个推理和解释管道,提供可操作的、领域基础的诊断。使用来自美国网络运营商的三个月真实城市级5G KPM数据集进行评估,TelcoAgent在200个单元中针对每个单元的7个KPM均展示了高预测准确性,同时提供了可解释的见解和可操作的指令来解决网络退化问题。

英文摘要

Key Performance Measurement (KPM) forecasting is essential for proactive network management of 5G and next-generation telecom networks. However, existing machine learning (ML) approaches face significant limitations in scalability and explainability, restricting their effectiveness in real-world deployments. We propose TelcoAgent, a foundation model-based framework that enables accurate, scalable, and explainable forecasting of multiple KPMs across diverse network cells without the need for site-specific training. Specifically, the framework comprises three key components: (i) an automated three-agent pipeline that constructs a 3rd Generation Partnership Project (3GPP) knowledge graph directly from specification documents, (ii) a scalable, time-series foundation model (TSFM)-based prediction pipeline to deliver accurate, zero-shot forecasting, and finally (iii) a reasoning and explanation pipeline that provides actionable, domain-grounded diagnostics. Evaluated using a 3-month, real-world, city-scale 5G KPM dataset from a U.S.-based network operator, TelcoAgent demonstrates high forecasting accuracy for all 7 considered KPMs per cell across 200 cells, while delivering explainable insights and actionable instructions to address network degradations.

将复合句分解为原子化的、可验证的声明是可靠自动化事实核查的前提。先前工作依赖基于词重叠(Jaccard)的度量,系统性地低估了释义声明的分解质量,并且缺乏对修复循环的形式化终止分析。我们提出CREDENCE,一个改进的声明分解与评估框架,解决了这两个缺陷。我们的贡献包括:(1) 语义F1:我们使用BGE-large余弦相似度保真度度量,解决了Jaccard的惩罚问题,并提高了下游事实核查的准确性;(2) 收敛定理:我们形式化地表征了修复管道的四个性质,确立了在预言解析器假设下基于规则的修复是单调且有限终止的;基于LLM的自修复被证明是非单调的,需要早期退出保护;(3) 三个评估基准,涵盖社交媒体、百科全书和新闻领域,用于跨领域泛化度量;(4) 跨四个分解器模型(3.8B-12B)和一个封闭API模型的多模型基准测试。在SocialClaimSplit、WikiSplitBench和ClaimDecompBench上的实验表明,语义F1比Jaccard F1提升15-32个百分点。在SocialClaimSplit和WikiSplitBench上,EPR范围为0.94至1.00,而ClaimDecompBench由于更难的新闻领域构造,包含较低的基线EPR情况(低至0.824),规则修复相对于基线模型将原子性违反率(AVR)降低了47-100%,且不降低保真度。

英文摘要

Decomposing compound sentences into atomic, verifiable claims is a prerequisite for reliable automated fact-checking. Prior work has relied on token-overlap (Jaccard) metrics that systematically underestimate decomposition quality for paraphrastic claims, and has lacked formal termination analysis for the repair loop. We present Credence, a revised claim decomposition and evaluation framework addressing both shortcomings. Our contributions are: (1) Semantic-F1: we use BGE-large cosine similarity fidelity metric that resolves Jaccard's penalisation and improves downstream fact-checking accuracy; (2) Convergence theorems: we formally characterise four properties of the repair pipeline, establishing that rule-based repair is monotone and finitely terminating under an oracle parser assumption; LLM-based self-repair is provably non-monotone and requires an early-exit guard; (3) Three evaluation benchmarks spanning social-media, encyclopaedic, and news domains for cross-domain generalisation measurement; (4) Multi-model benchmarking across four decomposer models (3.8B-12B) and a closed API model. Experiments on SocialClaimSplit, WikiSplitBench, and ClaimDecompBench show that Semantic-F1 outperforms Jaccard-F1 by +15-32pp. EPR ranges from 0.94 to 1.00 on SocialClaimSplit and WikiSplitBench, while ClaimDecompBench includes lower base EPR cases (down to 0.824) due to harder news-domain constructions, and rule-repair reduces the Atomicity Violation Rate (AVR) by 47-100% relative to the base model without degrading fidelity.

详情
AI中文摘要

从人类反馈中强化学习(RLHF)通过在偏好数据上训练奖励模型并优化策略以最大化预测奖励来对齐大型语言模型。然而,该流程面临两个基本挑战:(1)奖励模型无法在预测不可靠时发出信号,因为它们通常充当确定性点估计器;(2)现代基于组的策略优化可能放大不可靠的奖励信号,例如GRPO在优势计算中对奖励的统一处理。随着策略探索越来越多样化的响应,这两个限制造成了一个关键漏洞:不可靠的奖励估计可能被赋予不成比例的影响力,引发严重的奖励黑客问题。我们提出不确定性感知奖励建模(UARM),通过基于分位数的保形预测为奖励模型配备校准的不确定性,并通过异方差方差分解重加权GRPO优势。在HelpSteer、UltraFeedback和PKU-SafeRLHF上的实验表明,与标准GRPO和不确定性无关的基线相比,UARM显著改善了奖励模型校准,减少了奖励黑客问题,并增强了下游对齐质量。

英文摘要

Reinforcement learning from human feedback (RLHF) aligns large language models by training reward models on preference data and optimizing policies to maximize predicted rewards. However, this pipeline faces two fundamental challenges: (1) reward models cannot signal when their predictions are unreliable, since they usually act as deterministic point estimators; and (2) modern group-based policy optimization can amplify unreliable reward signals, as exemplified by GRPO's uniform treatment of rewards during advantage computation. As policies explore increasingly diverse responses, these two limitations create a critical vulnerability: unreliable reward estimates may be granted disproportionate influence, triggering severe reward hacking. We propose Uncertainty-Aware Reward Modeling (UARM), which equips reward models with calibrated uncertainty via quantile-based conformal prediction and reweights GRPO advantages through heteroscedastic variance decomposition. Experiments across HelpSteer, UltraFeedback, and PKU-SafeRLHF demonstrate that UARM significantly improves reward model calibration, reduces reward hacking, and enhances downstream alignment quality compared to standard GRPO and uncertainty-agnostic baselines.

随着近期图像生成模型的出现,合成数据越来越多地被用于补充有限的真实数据集,以训练计算机视觉模型。然而,并非所有合成数据集都能同等提升性能,其有效性只能通过训练下游模型来评估,这计算成本高且耗时。这个问题在目标检测任务中尤为突出,因为边界框所需的标注更为密集。在本文中,我们提出了一种可预先计算的度量族,称为条件-组合域匹配(CCDM),作为候选合成训练集对下游检测相对效用的代理指标。在VisDrone-DET数据集上的实验表明,CCDM度量族与YOLOv8的下游性能实现了1.0的Spearman相关性,明显优于现有的合成图像评估度量。

英文摘要

With the recent advent of image generative models, synthetic data are increasingly being used to supplement limited real datasets for training computer vision models. However, not all synthetic datasets improve performance equally, and their effectiveness can only be assessed by training a downstream model, which is computationally expensive and time-consuming. This problem is pronounced in the task of object detection, where the required annotations are much more dense due to bounding boxes. In this paper, we propose a pre-computable metric family, dubbed Conditional-Composition Domain Match (CCDM), which serves as a proxy for the relative utility of candidate synthetic training sets for downstream detection. Experiments on the VisDrone-DET dataset show that the CCDM metric families achieve a Spearman correlation of 1.0 with the downstream performance of YOLOv8, clearly outperforming existing metrics for synthetic image evaluation.

AI中文摘要

世界各地正在制定公共政策,以应对AI技术带来的隐私、经济、知识产权、能源及其他风险。公众参与作为问责和对齐机制,对治理至关重要。然而,对于缺乏广泛网络、游说能力及其他权力形式的公众群体来说,参与并影响政策制定可能具有挑战性。这一挑战对边缘化社区尤为严峻。本文通过我们组织将参与式设计(PD)原则引入美国AI政策制定的努力进行案例研究。我们描述了与多个美国政策机构的互动,以及为性少数群体参与式开发AI政策的过程。我们强调了与边缘化社区进行PD实践中的挑战,并提出了缓解这些挑战的建议。最后,我们为政策制定者及其他在边缘化社区工作的组织者提供了可行的建议。

英文摘要

Public policies are being developed around the world to address privacy, economic, intellectual property, energy, and other risks that AI technologies pose. Involvement from the general public is essential to governance as an accountability and alignment mechanism. However, participating in and impacting policymaking can be challenging for sections of the public that lack extensive networks, lobbying capabilities, and other forms of power. This challenge is especially acute for marginalized communities. In this paper, we present a case study of our organization's efforts to bring participatory design (PD) principles to AI policymaking in the US. We describe our engagements with several US policy bodies, and our participatory development of AI policy for queer people. We highlight challenges with PD practice with marginalized communities, and offer suggestions to alleviate them. We conclude with actionable recommendations for policymakers and other organizers working in marginalized communities.

AI总结 提出一种语义预训练框架,通过K-means或Top2Vec将文本聚类,用聚类-样本对预训练Tsetlin Machine,使其学习可解释的语义关键词,在五个数据集上性能优于传统方法且与BERT竞争。

详情
AI中文摘要

预训练语言模型如BERT在文本分类任务中表现强劲,但缺乏透明度,限制了在高风险场景中的应用。Tsetlin Machine (TM) 提供完全可解释的基于子句的推理,但捕获的语义信息有限,先前桥接两者的尝试依赖于静态词嵌入,忽略了上下文含义。我们提出一种语义预训练框架,无需使用嵌入即可将知识从预训练语言模型转移到TM中。文本样本通过K-means或Top2Vec被分组为语义一致的聚类,得到的聚类-样本对通过增强的Type I反馈预训练一个非否定TM。因此,TM学习到可解释的语义关键词,并在下游任务上进行微调。在五个数据集上,我们的方法显著优于传统和基于嵌入的TM,性能与BERT竞争,同时保持可解释性。

英文摘要

Pre-trained language models such as BERT achieve strong text classification performance but lack transparency, limiting their use in high-stakes settings. The Tsetlin Machine (TM) offers fully interpretable, clause-based reasoning but captures little semantic information, and prior attempts to bridge the two rely on static word embeddings that miss contextual meaning. We propose a semantic pre-training framework that transfers knowledge from a pre-trained language model into a TM without using embeddings. Text samples are grouped into semantically coherent clusters with K-means or Top2Vec, and the resulting cluster-sample pairs pre-train a non-negated TM with enhanced Type I feedback. The TM thereby learns interpretable semantic keywords that are fine-tuned on downstream tasks. Across five datasets, our method substantially outperforms vanilla and embedding-based TMs and reaches performance competitive with BERT while remaining interpretable.

Chaoran Cai, Bo Xiong, Chong Wang, Lulu He, Peng Liang

AI总结 提出 CoRaCommit VS Code 扩展,通过检索相似提交范例作为提示上下文、并行调用多个大语言模型生成候选消息并基于用户反馈动态推荐,在 ApacheCM 数据集上优于现有扩展。

AI中文摘要

提交消息是描述代码变更意图的关键文本制品,在版本控制、代码审查和历史追踪中扮演重要角色。然而,实践中提交消息主要由人工编写,耗时且常导致质量不一致和表达不统一。现有的用于提交消息生成的 VS Code 扩展通常直接基于代码差异调用大语言模型,而不利用相似提交范例作为参考,且很少支持用户反馈驱动的大语言模型推荐。为解决这些局限,本文提出 CoRaCommit,一种 VS Code 扩展,通过检索相似提交范例作为提示上下文、并行调用多个大语言模型进行候选提交消息比较,并基于用户反馈动态推荐大语言模型,从而增强提交消息生成。在 ApacheCM 数据集的 945 个提交上的实验结果表明,CoRaCommit 在 BLEU、CIDEr、METEOR 和 ROUGE-L 指标上优于现有 VS Code 扩展,证明了检索增强上下文对提交消息生成的有效性。

英文摘要

Commit messages are essential textual artifacts that describe the intent behind code changes, and play a critical role in version control, code review, and historical tracking. However, in practice, commit messages are primarily authored manually, which is time-consuming and often results in inconsistent quality and non-uniform expression. Existing VS Code extensions for commit message generation typically directly invoke large language models based on the code diff, without leveraging similar commit exemplars as references, and rarely support user feedback-driven LLM recommendation. To address these limitations, this paper presents CoRaCommit, a VS Code extension that enhances commit message generation by retrieving similar commit exemplars as prompt context, invoking multiple LLMs in parallel for candidate commit message comparison, and dynamically recommending LLMs based on user feedback. Experimental results on 945 commits from the ApacheCM dataset show that CoRaCommit outperforms existing VS Code extensions across BLEU, CIDEr, METEOR, and ROUGE-L metrics, demonstrating the effectiveness of retrieval-augmented context for commit message generation.

TIDY: Thermal Infrared Image Denoising via Wavelet Domain Entropy and Directional Stripe Index

TIDY: 基于小波域熵和方向条纹指数的热红外图像去噪

发表机构 * Dept. of Mechanical Engineering, SNU(首尔大学机械工程系)

AI总结 提出轻量级小波域去噪器TIDY,利用真实噪声数据训练,通过小波熵和方向条纹指数损失项抑制随机噪声和条纹伪影,在室内恶劣条件下提升热红外图像质量及下游机器人任务性能。

详情
AI中文摘要

热红外(TIR)成像因其在低光视觉退化下的鲁棒感知能力,已成为野外机器人的热门选择,但它受到严重的随机噪声和固定模式噪声的影响,破坏了后续估计。由于低热对比度和均匀温度分布,这种噪声在室内会加剧,导致室内TIR部署相对缺乏。现有的TIR去噪方法在精度和效率之间权衡不佳,要么对于机器人所需的在线部署来说太慢,要么对严重退化不够鲁棒,而且通常是在合成噪声上训练的。针对这些问题,我们提出了TIDY,一种轻量级的小波域去噪器,在真实的干净-噪声TIR数据上训练。通过在小波域中重新表述TIR去噪,TIDY明确地将噪声与结构内容分离,实现了有针对性的抑制,降低了空间复杂度,显著提高了推理速度(约34Hz)。TIDY引入了两个新指标,小波熵和小波方向条纹指数,作为互补的损失项,以明确抑制随机噪声和条纹伪影。在严重的室内损坏和零样本设置中,TIDY提高了鲁棒性,并在下游机器人任务(包括热惯性里程计和单目深度估计)中产生一致的增益。代码和数据集可在以下网址获取:this https URL

英文摘要

Thermal infrared (TIR) imaging has been a popular choice for field robotics due to its robust perception capability under low light visual degradation, but it suffers from severe stochastic and fixed-pattern noise that breaks downstream estimation. This noise is intensified indoors due to low thermal contrast and uniform temperature distributions, contributing to the relative lack of indoor TIR deployments. Existing TIR denoising methods exhibit a poor accuracy-efficiency tradeoff, either too slow for online deployment required in robotics or insufficiently robust to severe degradation, while typically being trained on synthetic noise. Addressing these problems, we propose TIDY, a lightweight wavelet-domain denoiser trained on real clean-noisy TIR data. By reformulating TIR denoising in the wavelet domain, TIDY explicitly disentangles noise from structural content, enabling targeted suppression with reduced spatial complexity, significantly improving inference speed over prior methods (~34Hz). TIDY introduces two new metrics, Wavelet Entropy and Wavelet Directional Stripe Index, as complementary loss terms to explicitly suppress stochastic noise and stripe artifacts. Across severe indoor corruption and zero-shot settings, TIDY improves robustness and yields consistent gains in downstream robotics tasks including thermal inertial odometry and monocular depth estimation.

AI总结 针对AI代理在电子取证中因多步推理错误导致的法律风险,提出一种四层验证架构,通过人机协同阈值减少特权豁免风险达61%。

详情
AI中文摘要

自主大语言模型(LLM)代理越来越多地部署于电子发现(e-discovery),其中跨多步推理链的复合错误可能构成法律渎职。与单轮检索不同,在特权文档语料库上运行的代理工作流表现出我们称之为“轨迹崩溃”的一类失败:早期错误分类无声传播,导致整个特权审查失效。本文做出三项贡献。首先,我们提出一个按功能阶段组织的法律信息检索中代理失败的结构化分类法。其次,我们引入一个四层验证架构——涵盖规划、推理、执行和不确定性量化——旨在这些失败复合之前拦截它们。第三,我们在一个合成电子取证语料库上进行初步模拟研究,展示强制性人机协同(HOTL)升级阈值如何相对于完全自主基线降低特权豁免风险。我们的结果表明,与完全自主部署相比,校准的不确定性阈值可将特权豁免风险降低高达61%,同时将不到四分之一的文档路由给律师审查。

英文摘要

Autonomous Large Language Model (LLM) agents are increasingly deployed in electronic discovery (e-discovery), where compounding errors across multi-step reasoning chains can constitute legal malpractice. Unlike single-turn retrieval, agentic workflows operating over privileged document corpora exhibit a class of failure we term "trajectory collapse": an early misclassification silently propagates, rendering an entire privilege review invalid. This paper makes three contributions. First, we propose a structured taxonomy of agentic failures in legal information retrieval, organized by functional stage. Second, we introduce a four-layer verification architecture -- spanning planning, reasoning, execution, and uncertainty quantification -- designed to intercept these failures before they compound. Third, we present a preliminary simulation study on a synthetic e-discovery corpus that demonstrates how mandatory Human-on-the-Loop (HOTL) escalation thresholds reduce privilege-waiver risk relative to fully autonomous baselines. Our results suggest that calibrated uncertainty thresholds can reduce privilege-waiver risk by up to 61% versus fully autonomous deployment, while routing fewer than one quarter of documents to attorney review.

AI总结 提出选择性验证框架SEVRA,通过服务层控制器决定是否对冻结求解器的初始答案进行验证,在Math500上以更少token达到更高准确率,并减少有害翻转。

详情
AI中文摘要

测试时推理越来越多地被用作服务时的控制旋钮,但额外的推理并非均匀有价值:它可以修复失败的尝试,在已经正确的答案上浪费计算,或引入有害的答案更改。我们将其视为一个部署分配问题,而非新验证器问题。我们引入SEVRA,即面向推理分配的选择性验证,这是一个服务层控制器,决定是保留冻结求解器的初始答案还是调用主动验证。使用冻结的Qwen3-4B求解器,我们记录干预结果并从服务可见的尝试状态训练可恢复性感知的门控。在Math500上,选择性验证达到76.3%的准确率,而始终验证为75.5%,同时将生成后token减少26.8%,有害翻转从2.2%降至1.0%。然而,8,192 token的初始求解达到76.0%的准确率,总模型token减少28%,表明选择性恢复有用但并非测试的最佳成本前沿。在冻结迁移到GSM时,选择性策略仅验证3.0%的样本,准确率从93.4%提升至94.5%,验证token相对于始终验证减少91.2%;同样,更长的初始求解以更少的实际token达到相同准确率。在CommonsenseQA上,始终开启的验证有害,而Self-Consistency@5以约五倍的实际token成本提升准确率。由此得出的部署规则是:首先调整初始预算,然后在需要显式检查、有限重试、可审计性或回归风险控制时使用选择性恢复。

英文摘要

Test-time reasoning is increasingly used as a serving-time control knob, but extra reasoning is not uniformly valuable: it can repair failed attempts, waste compute on already-correct answers, or introduce harmful answer changes. We study this as a deployment allocation problem rather than a new-verifier problem. We introduce \sevra, Selective Verification for Reasoning Allocation, a serving-layer controller that decides whether to preserve a frozen solver's initial answer or invoke active verification. Using a frozen Qwen3-4B solver, we log intervention outcomes and train recoverability-aware gates from serving-visible attempt state. On \mathfive, selective verification reaches 76.3\% accuracy, compared with 75.5\% for always verifying, while reducing post-generation tokens by 26.8\% and harmful flips from 2.2\% to 1.0\%. However, an 8,192-token initial solve reaches 76.0\% accuracy with 28\% fewer total model tokens, showing that selective recovery is useful but not the best tested cost frontier. In frozen transfer to \gsm, the selective policy verifies only 3.0\% of examples, improves accuracy from 93.4\% to 94.5\%, and reduces verification tokens by 91.2\% relative to always verifying; again, a longer initial solve matches its accuracy with fewer realized tokens. On CommonsenseQA, always-on verification hurts, while Self-Consistency@5 improves accuracy at about five times the realized token cost. The resulting deployment rule is: tune the initial budget first, then use selective recovery when explicit checks, bounded retries, auditability, or regression-risk control matter.

DISARM: Target Electronic Device Informed Mitigation of Software Runtime Side-Channel Vulnerabilities

DISARM:目标电子设备知情的软件运行时侧信道漏洞缓解

Tasneem Suha, Tanzim Mahfuz, Rima Asmar Awad, Prabuddha Chakraborty

AI总结 提出DISARM方法,利用真实嵌入式设备时序值生成针对性软件修复,以缓解运行时侧信道漏洞,在五个不同设备上优于现有方案。

详情
AI中文摘要

程序运行时或时序攻击利用程序执行时间的变化来提取敏感信息(如加密密钥、敏感变量数据、知识产权)。针对运行时侧信道攻击的最新解决方案试图平衡不同控制流路径下敏感代码的执行时间,以消除时序泄漏。然而,在缓解过程中,大多数技术未考虑目标程序运行的底层硬件或设备。这可能导致过度修复(不必要的额外操作)、修复不足(未正确解决不平衡)甚至失败。我们提出DISARM,一种联合硬件-软件方法(不同于任何现有解决方案),用于缓解运行时侧信道漏洞,该方法利用真实嵌入式设备的时序值生成针对性的软件修复。我们实现了DISARM以支持C、C++和Java源代码,并在22个标准基准测试上进行验证。在五个不同的嵌入式或边缘设备上,DISARM在执行时间开销、代码大小开销和正确性方面均优于现有解决方案如PENDULUM和DifFuzzAR。

英文摘要

Program runtime or timing attacks exploit variations in a program's execution times to extract sensitive information from the program (e.g. encryption keys, sensitive variable data, intellectual property). State-of-the-art solutions to runtime side-channel attacks attempt to balance the execution time of the sensitive code for different control flow paths to eliminate the timing leakage. However, during the mitigation process, most techniques do not consider the underlying hardware or device on which the target program is supposed to run on. This can lead to over-fixing (unnecessary extra operations), under-fixing (not solving the imbalance properly), and even failures. We propose DISARM, a joint hardware-software methodology (unlike any existing solution) for mitigating runtime side-channel vulnerabilities that utilizes timing values from real embedded devices to generate targeted software fixes. We implement DISARM to support C, C++, and Java source codes and validate it across 22 standard benchmarks. DISARM outperforms state-of-the-art solutions such as PENDULUM and DifFuzzAR in terms of execution time overhead, code size overhead, and correctness on five different embedded or edge devices.

Zijie Meng

发表机构 * Peking University(北京大学)

AI总结 提出ParaScale模块,通过规范不变的视差数Pi实现尺度忠实相机运动迁移,无需重新训练,在四个数量级尺度上降低视差一致性误差3倍以上。

Comments Accepted by SCA2026(poster)

AI中文摘要

将参考视频的相机运动迁移到新生成的视频中,可以让创作者重复使用电影级运镜。然而,参考视频和目标视频往往处于不兼容的尺度——例如跨越银河系的扫视与桌面上的轻推——直接复用恢复的轨迹会导致运动要么不可察觉,要么剧烈夸张。我们将此归结为一个几何事实:平移引起的图像运动与||T||/Z成比例,因此单目轨迹仅在深度尺度规范下才有意义。我们将此提炼为视差数Pi = ||Delta T|| / Zbar,这是一个无量纲、规范不变的描述符,用于衡量相机运动的感知强度,并证明它是尺度忠实迁移必须保持的量,而非原始轨迹。ParaScale是一个即插即用模块,它从任何参考视频中读取Pi,并针对目标场景的深度逐帧重新实现它,保持旋转不变。它位于姿态提取和姿态注入之间,无需重新训练,可插入任何姿态条件生成器。我们进一步引入了视差一致性误差(PCE),这是一种尺度对称的度量,与相似性对齐的TransErr不同,它能暴露场景尺度不匹配。在跨越四个数量级的尺度范围和多个骨干网络上,ParaScale将实现的视差保持在恒等线上,并将PCE比未校准的迁移降低3倍以上,且不损失视觉保真度。

英文摘要

Transferring the camera motion of a reference video to a freshly generated one lets creators reuse cinematic moves. Yet reference and target often live at incompatible scales -- a sweep across a galaxy versus a nudge across a desk -- and naively reusing the recovered trajectory yields either imperceptible or violently exaggerated motion. We trace this to a geometric fact: translation-induced image motion scales as ||T||/Z, so a monocular trajectory is meaningful only up to a depth-scale gauge. We distill this into the Parallax Number Pi = ||Delta T|| / Zbar, a dimensionless, gauge-invariant descriptor of how strongly a camera move is felt, and prove that it -- not the raw trajectory -- is the quantity that scale-faithful transfer must preserve. ParaScale is a plug-and-play module that reads Pi off any reference video and re-realizes it against the target scene's own depth, per frame, leaving rotation untouched. Sitting between pose extraction and pose injection, it requires no retraining and drops into any pose-conditioned generator. We further introduce the Parallax Consistency Error (PCE), a scale-symmetric metric that -- unlike the similarity-aligned TransErr -- exposes scene-scale mismatch. Across scale regimes spanning four orders of magnitude and multiple backbones, ParaScale keeps the realized parallax on the identity line and cuts PCE by more than 3x over uncalibrated transfer with no loss of visual fidelity.
