AI中文摘要

不确定性感知深度学习模型最近在故障诊断中受到关注,作为一种在来自未见故障(认知不确定性)或噪声存在(偶然不确定性)的分布外数据出现时促进可靠故障检测的方法。在本文中,我们首次对旋转机械故障诊断中最先进的不确定性感知深度学习架构进行了全面比较研究,其中研究了受认知不确定性影响的不同场景和不同类型的偶然不确定性。所选架构包括通过dropout采样、贝叶斯神经网络和深度集成。此外,为了区分不同场景中的分布内和分布外数据,我们交替应用了两个不确定性阈值,其中一个是在本文中引入的。我们的实证结果为必须部署实际不确定性感知故障诊断系统的从业者和研究人员提供了指导。特别是,它们揭示了在存在认知不确定性的情况下,所有深度学习模型都能够有效地检测到平均而言所有场景中相当一部分分布外数据。然而,深度集成模型显示出优越的性能,与用于区分的阈值无关。在存在偶然不确定性的情况下,噪声水平起着重要作用。具体来说,低噪声水平阻碍了模型有效检测分布外数据的能力。即使在这种情况下,深度集成模型也表现出较温和的性能下降,主导其他模型。这些成就,加上它们更短的推理时间,使得深度集成架构成为首选。

英文摘要

Uncertainty-aware deep learning (DL) models recently gained attention in fault diagnosis as a way to promote the reliable detection of faults when out-of-distribution (OOD) data arise from unseen faults (epistemic uncertainty) or the presence of noise (aleatoric uncertainty). In this paper, we present the first comprehensive comparative study of state-of-the-art uncertainty-aware DL architectures for fault diagnosis in rotating machinery, where different scenarios affected by epistemic uncertainty and different types of aleatoric uncertainty are investigated. The selected architectures include sampling by dropout, Bayesian neural networks, and deep ensembles. Moreover, to distinguish between in-distribution and OOD data in the different scenarios two uncertainty thresholds, one of which is introduced in this paper, are alternatively applied. Our empirical findings offer guidance to practitioners and researchers who have to deploy real-world uncertainty-aware fault diagnosis systems. In particular, they reveal that, in the presence of epistemic uncertainty, all DL models are capable of effectively detecting, on average, a substantial portion of OOD data across all the scenarios. However, deep ensemble models show superior performance, independently of the uncertainty threshold used for discrimination. In the presence of aleatoric uncertainty, the noise level plays an important role. Specifically, low noise levels hinder the models' ability to effectively detect OOD data. Even in this case, however, deep ensemble models exhibit a milder degradation in performance, dominating the others. These achievements, combined with their shorter inference time, make deep ensemble architectures the preferred choice.

AI中文摘要

多模光纤是头发丝粗细的玻璃丝,能高效传输光。它们有望实现下一代医用内窥镜,在体内深处提供前所未有的亚细胞图像分辨率。然而,将光限制在这样的光纤中意味着图像在传输过程中固有地被打乱。传统上,通过预先校准特定光纤如何打乱光并求解表示光纤物理模型的静态线性矩阵方程来补偿这种打乱。然而,随着技术向实际部署发展,解扰过程必须考虑由于移动和温度变化等因素导致的光纤对光影响的矩阵的动态变化,以及由于光纤尖端在体内不可及而产生的非线性。这种复杂、动态和非线性行为非常适合用神经网络近似,但大多数领先的图像重建网络依赖卷积层,这些层假设相邻像素之间存在强相关性,这种强归纳偏置不适用于光纤矩阵,因为光纤矩阵可以用具有长程相关性的任意坐标表示来表达。我们引入了一个新概念,使用自注意力层将变化的光纤矩阵的坐标表示动态变换到允许紧凑、低维表示的基,适合进一步处理。我们在不同的光纤矩阵数据集上展示了该方法的有效性。我们展示了我们的模型在变换基上显著提高了光纤基的稀疏性,以参与比p作为稀疏性度量,介于0.01和0.11之间。此外,我们展示了这些变换后的表示允许以<10%的重建误差重建原始矩阵,证明了可逆性。

英文摘要

Multimode optical fibres are hair-thin strands of glass that efficiently transport light. They promise next-generation medical endoscopes that provide unprecedented sub-cellular image resolution deep inside the body. However, confining light to such fibres means that images are inherently scrambled in transit. Conventionally, this scrambling has been compensated by pre-calibrating how a specific fibre scrambles light and solving a stationary linear matrix equation that represents a physical model of the fibre. However, as the technology develops towards real-world deployment, the unscrambling process must account for dynamic changes in the matrix representing the fibre's effect on light, due to factors such as movement and temperature shifts, and non-linearities resulting from the inaccessibility of the fibre tip when inside the body. Such complex, dynamic and nonlinear behaviour is well-suited to approximation by neural networks, but most leading image reconstruction networks rely on convolutional layers, which assume strong correlations between adjacent pixels, a strong inductive bias that is inappropriate for fibre matrices which may be expressed in a range of arbitrary coordinate representations with long-range correlations. We introduce a new concept that uses self-attention layers to dynamically transform the coordinate representations of varying fibre matrices to a basis that admits compact, low-dimensional representations suitable for further processing. We demonstrate the effectiveness of this approach on diverse fibre matrix datasets. We show our models significantly improve the sparsity of fibre bases in their transformed bases with a participation ratio, p, as a measure of sparsity, of between 0.01 and 0.11. Further, we show that these transformed representations admit reconstruction of the original matrices with < 10% reconstruction error, demonstrating the invertibility.

AI中文摘要

从基础模型向紧凑领域模型进行知识蒸馏因能力、架构和模态的巨大差异而具有挑战性。例如,在我们的实验中,从7600万参数的语言模型蒸馏到200万参数的推荐模型仅能弥补未蒸馏学生与教师之间不到40%的性能差距。我们表明,引入与基础模型共享学生架构特征的领域专家作为多样化教师委员会,能显著改善迁移效果。然而,标准的多教师方法未能利用这种多样性:简单组合异构教师可能使性能低于单教师蒸馏。为此,我们提出DiverseDistill,一种交互式蒸馏框架,采用可学习的问答机制生成教师条件查询,并将异构教师输出对齐到学生的表示空间。与需要基于梯度的协同优化或修改教师架构的方法不同,DiverseDistill在冻结教师的情况下仅通过其中间层的前向推理运行:无需参数更新、无需协同训练、无需架构修改。动态教师重要性机制通过过滤每个样本中低相关性的教师(例如,在推荐任务中减少约30%的前向传播且无质量损失)进一步降低训练成本,而整个蒸馏模块在训练后被丢弃,推理时零开销。在推荐(38倍压缩)和视觉(3.6倍压缩)任务上的评估表明,DiverseDistill恢复了73-114%的师生性能差距,持续优于所有单教师和多教师基线方法。

英文摘要

Knowledge distillation from foundation models to compact domain models is challenging due to substantial gaps in capacity, architecture, and modality. For example, in our experiments, distilling from a 76M-parameter language model to a 2M-parameter recommender closes less than 40% of the performance gap between the undistilled student and the teacher. We show that introducing domain-specific experts -- which share the student's architectural characteristics -- alongside the foundation model as a diverse teacher committee significantly improves transfer. However, standard multi-teacher methods fail to exploit this diversity: naively combining heterogeneous teachers can degrade performance below single-teacher distillation. To address this, we propose DiverseDistill, an interactive distillation framework that employs a learnable Question-Answer mechanism to generate teacher-conditioned queries and align heterogeneous teacher outputs into the student's representation space. Unlike methods requiring gradient-based co-optimization or architectural modification of teachers, DiverseDistill operates with frozen teachers using only forward-pass inference through their intermediate layers: no parameter updates, no co-training, and no architectural surgery. A dynamic teacher importance mechanism further reduces training cost by filtering low-relevance teachers per sample (e.g., ~30% fewer forward passes with no quality loss for recommendation tasks), while the entire Distillation Module is discarded after training, adding zero inference overhead. Evaluations on recommendation (38x compression) and vision (3.6x compression) tasks demonstrate that DiverseDistill recovers 73-114% of the teacher-student performance gap, consistently outperforming all single- and multi-teacher baselines.

英文摘要

Target-group detection is the task of detecting which group(s) a piece of content is ``directed at or about''. Applications include targeted marketing, content recommendation, and group-specific content assessment. Key challenges include: 1) that a single post may target multiple groups; and 2) ensuring consistent detection accuracy across groups for fairness. In this work, we investigate fairness implications of target-group detection in the context of toxicity detection, where the perceived harm of a social media post often depends on which group(s) it targets. Because toxicity is highly contextual, language that appears benign in general can be harmful when targeting specific demographic groups. We show our {\em fairness-aware multi-group target detection} approach both reduces bias across groups and shows strong predictive performance, surpassing existing fairness-aware baselines. To enable reproducibility and spur future work, we share our code online.

英文摘要

3D Gaussian Splatting (3DGS) has emerged as a powerful technique for generating photorealistic renderings of a scene in real-time. However, the volumetric nature of 3DGS limits its ability to accurately capture surface geometry. To address this, 2D Gaussian Splatting (2DGS) was proposed to enable view-consistent and geometrically accurate surface reconstruction from multi-view images. However, 2DGS can be sensitive to the initialization of the Gaussian primitives. Reliance on Structure-from-Motion (SfM) initializations, which can produce poor estimates on challenging image sets, may lead to subpar results. In this work, we enhance 2DGS by incorporating monocular depth and normal priors to improve both geometric accuracy and robustness. We propose a depth-guided initialization strategy for Gaussians and introduce a clustering-based technique for pruning degenerate Gaussians. We evaluate our method on the DTU dataset, where it achieves state-of-the-art results in mesh reconstruction while preserving high-quality novel view synthesis.

英文摘要

There are two prevalent model-based paradigms for combinatorial problems: 1) state-based representations, such as heuristic search, dynamic programming (DP), and decision diagrams, and 2) constraint and domain-based representations, such as constraint programming (CP), (mixed-)integer programming, and Boolean satisfiability. In this paper, we bridge the gap between the DP and CP paradigms by integrating constraint propagation into DP, enabling a DP solver to prune states and transitions using constraint propagation. To this end, we implement constraint propagation using a general-purpose CP solver in the Domain-Independent Dynamic Programming framework and evaluate using heuristic search on three combinatorial optimisation problems: Single Machine Scheduling with Time Windows, the Resource Constrained Project Scheduling Problem (RCPSP), and the Travelling Salesperson Problem with Time Windows (TSPTW). Our evaluation shows that constraint propagation significantly reduces the number of state expansions, causing our approach to solve more instances than a DP solver for Single Machine Scheduling and RCPSP, and showing similar improvements for tightly constrained TSPTW instances. The runtime performance indicates that the benefits of propagation outweigh the overhead for constrained instances, but that further work into reducing propagation overhead could improve performance further. Our work is a key step in understanding the value of constraint propagation in DP solvers, providing a model-based approach to integrating DP and CP.

英文摘要

Reading scene text, that is, text appearing in images, has numerous application areas, including assistive technology, search, and e-commerce. Although scene text recognition in English has advanced significantly and is often considered nearly a solved problem, Indian language scene text recognition remains an open challenge. This is due to script diversity, non-standard fonts, and varying writing styles, and, more importantly, the lack of high-quality datasets and open-source models. To address these gaps, we introduce the Bharat Scene Text Dataset (BSTD) - a large-scale and comprehensive benchmark for studying Indian Language Scene Text Recognition. It comprises more than 100K words that span 11 Indian languages and English, sourced from over 6,500 scene images captured across various linguistic regions of India. The dataset is meticulously annotated and supports multiple scene text tasks, including: (i) Scene Text Detection, (ii) Script Identification, (iii) Cropped Word Recognition, and (iv) End-to-End Scene Text Recognition. We evaluated state-of-the-art models originally developed for English by adapting (fine-tuning) them for Indian languages. Our results highlight the challenges and opportunities in Indian language scene text recognition. We believe that this dataset represents a significant step toward advancing research in this domain. All our models and data are open source.

英文摘要

Reading the Herculaneum papyri is challenging because both the scrolls and the ink, which is carbon-based, are carbonized. In X-ray radiography and tomography, ink detection typically relies on density- or composition-driven contrast, but carbon ink on carbonized papyrus provides little attenuation contrast. Building on the morphological hypothesis, we show that the surface morphology of written regions contains enough signal to distinguish ink from papyrus. To this end, we train machine learning models on three-dimensional optical profilometry from mechanically opened Herculaneum papyri to separate inked and uninked areas. We further quantify how lateral sampling governs learnability and how a native-resolution model behaves on coarsened inputs. We show that high-resolution topography alone contains a usable signal for ink detection. Diminishing segmentation performance with decreasing lateral resolution provides insight into the characteristic spatial scales that must be resolved on our dataset to exploit the morphological signal. These findings inform spatial resolution targets for morphology-based reading of closed scrolls through X-ray tomography.

英文摘要

Autonomous proximity operations, such as active debris removal and on-orbit servicing, require high-fidelity relative navigation solutions that remain robust in the presence of parametric uncertainty. Standard estimation frameworks typically assume that the target spacecraft's mass properties are known a priori; however, for non-cooperative or tumbling targets, these parameters are often unknown or uncertain, leading to rapid divergence in model-based propagators. This paper presents an augmented Unscented Kalman Filter (UKF) framework designed to jointly estimate the relative 6-DOF pose and the full inertia tensor of a non-cooperative target spacecraft. The proposed architecture fuses visual measurements from monocular vision-based Convolutional Neural Networks (CNN) with depth information from LiDAR to constrain the coupled rigid-body dynamics. By augmenting the state vector to include the six independent elements of the inertia tensor, the filter dynamically recovers the target's normalized mass distribution in real-time without requiring ground-based pre-calibration. To ensure numerical stability and physical consistency during the estimation of constant parameters, the filter employs an adaptive process noise formulation that prevents covariance collapse while allowing for the gradual convergence of the inertial parameters. Numerical validation is performed via Monte Carlo simulations, demonstrating that the proposed Augmented UKF enables the simultaneous convergence of kinematic states and inertial parameters, thereby facilitating accurate long-term trajectory prediction and robust guidance in non-cooperative deep-space environments.

英文摘要

The digitalization of credit scoring has become essential for financial institutions and commercial banks, especially in the era of digital transformation. Machine learning techniques are commonly used to evaluate customers' creditworthiness. However, the predicted outcomes of machine learning models can be biased toward protected attributes, such as race or gender. Numerous fairness-aware machine learning models and fairness measures have been proposed. Nevertheless, their performance in the context of credit scoring has not been thoroughly investigated. In this paper, we present a comprehensive experimental study of fairness-aware machine learning in credit scoring. The study explores key aspects of credit scoring, including financial datasets, predictive models, and fairness measures. We also provide a detailed evaluation of fairness-aware predictive models and fairness measures on widely used financial datasets. The experimental results show that fairness-aware models achieve a better balance between predictive accuracy and fairness compared to traditional classification models.

英文摘要

Homographies are among the most prevalent transformations occurring in geometric computer vision and projective geometry, and homography estimation is consequently a crucial step in a wide assortment of computer vision tasks. When working with real images, which are often afflicted with geometric distortions caused by the camera lens, it may be necessary to determine both the homography and the lens distortion-particularly the radial component, called radial distortion-simultaneously to obtain anything resembling useful estimates. When considering a homography with radial distortion between two images, there are three conceptually distinct configurations for the radial distortion; (i) distortion in only one image, (ii) identical distortion in the two images, and (iii) independent distortion in the two images. While these cases have been addressed separately in the past, the present paper provides a novel and unified approach to solve all three cases. We demonstrate how the proposed approach can be used to construct new fast, stable, and accurate minimal solvers for radially distorted homographies. In all three cases, our proposed solvers are faster than the existing state-of-the-art solvers while maintaining similar accuracy. The solvers are tested on well-established benchmarks including images taken with fisheye cameras. A reference implementation of the proposed solvers is made available as part of HomLib (https://github.com/marcusvaltonen/HomLib).

英文摘要

Learning robust manipulation policies typically requires large and diverse datasets, the collection of which is time-consuming, labor-intensive, and often impractical for dynamic environments. In this work, we introduce DynaMimicGen (D-MG), a scalable dataset generation framework that enables policy training from minimal human supervision while uniquely supporting dynamic task settings. Given only a few human demonstrations, D-MG first segments the demonstrations into meaningful sub-tasks, then leverages Dynamic Movement Primitives (DMPs) to adapt and generalize the demonstrated behaviors to novel and dynamically changing environments. Improving prior methods that rely on static assumptions or simplistic trajectory interpolation, D-MG produces smooth, realistic, and task-consistent Cartesian trajectories that adapt in real time to changes in object poses, robot states, or scene geometry during task execution. Our method supports different scenarios - including scene layouts, object instances, and robot configurations - making it suitable for both static and highly dynamic manipulation tasks. We show that robot agents trained via imitation learning on D-MG-generated data achieve strong performance across long-horizon and contact-rich benchmarks, including tasks like cube stacking and placing mugs in drawers, even under unpredictable environment changes. By eliminating the need for extensive human demonstrations and enabling generalization in dynamic settings, D-MG offers a powerful and efficient alternative to manual data collection, paving the way toward scalable, autonomous robot learning.

Evaluating reasoning ability in Large Language Models (LLMs) is important for advancing artificial intelligence, as it transcends mere linguistic task performance. It involves understanding whether these models truly understand information, perform inferences, and are able to draw conclusions in a logical and valid way. This study compare logical and abstract reasoning skills of several LLMs - including GPT, Claude, DeepSeek, Gemini, Grok, Llama, Mistral, Perplexity, and Sabiá - using a set of eight custom-designed reasoning questions. The LLM results are benchmarked against human performance on the same tasks, revealing significant differences and indicating areas where LLMs struggle with deduction.

英文摘要

Automated cardiac interpretation in resource-constrained settings (RCS) is often hindered by poor-quality echocardiographic imaging, limiting the effectiveness of downstream diagnostic models. While super-resolution (SR) techniques have shown promise in enhancing magnetic resonance imaging (MRI) and computed tomography (CT) scans, their application to echocardiography-a widely accessible but noise-prone modality-remains underexplored. In this work, we investigate the potential of deep learning-based SR to improve classification accuracy on low-quality 2D echocardiograms. Using the publicly available CAMUS dataset, we stratify samples by image quality and evaluate two clinically relevant tasks of varying complexity: a relatively simple Two-Chamber vs. Four-Chamber (2CH vs. 4CH) view classification and a more complex End-Diastole vs. End-Systole (ED vs. ES) phase classification. We apply two widely used SR models-Super-Resolution Generative Adversarial Network (SRGAN) and Super-Resolution Residual Network (SRResNet), to enhance poor-quality images and observe significant gains in performance metric-particularly with SRResNet, which also offers computational efficiency. Our findings demonstrate that SR can effectively recover diagnostic value in degraded echo scans, making it a viable tool for AI-assisted care in RCS, achieving more with less.

英文摘要

Annually and globally, over three billion radiography examinations and computer tomography scans result in mostly unstructured radiology reports containing free text. Despite the potential benefits of structured reporting, its adoption is limited by factors such as established processes, resource constraints and potential loss of information. However, structured information would be necessary for various use cases, including automatic analysis, clinical trial matching, and prediction of health outcomes. This study introduces RadEx, an end-to-end framework comprising 15 software components and ten artifacts to develop systems that perform automated information extraction from radiology reports. It covers the complete process from annotating training data to extracting information by offering a consistent generic information model and setting boundaries for model development. Specifically, RadEx allows clinicians to define relevant information for clinical domains (e.g., mammography) and to create report templates. The framework supports both generative and encoder-only models and the decoupling of information extraction from template filling enables independent model improvements. Developing information extraction systems according to the RadEx framework facilitates implementation and maintenance as components are easily exchangeable, while standardized artifacts ensure interoperability between components.

Introduction: Microblogging websites have massed rich data sources for sentiment analysis and opinion mining. In this regard, sentiment classification has frequently proven inefficient because microblog posts typically lack syntactically consistent terms and representatives since users on these social networks do not like to write lengthy statements. Also, there are some limitations to low-resource languages. The Persian language has exceptional characteristics and demands unique annotated data and models for the sentiment analysis task, which are distinctive from text features within the English dialect. Method: This paper first constructs a user opinion dataset called ITRC-Opinion in a collaborative environment and insource way. Our dataset contains 60,000 informal and colloquial Persian texts from social microblogs such as Twitter and Instagram. Second, this study proposes a new architecture based on the convolutional neural network (CNN) model for more effective sentiment analysis of colloquial text in social microblog posts. The constructed datasets are used to evaluate the presented architecture. Furthermore, some models, such as LSTM, CNN-RNN, BiLSTM, and BiGRU with different word embeddings, including Fasttext, Glove, and Word2vec, investigated our dataset and evaluated the results. Results: The results demonstrate the benefit of our dataset and the proposed model (72% accuracy), displaying meaningful improvement in sentiment classification performance.

英文摘要

The diurnal cycle of tropical cyclones (TCs) is a daily cycle in clouds that appears in satellite images and may have implications for TC structure and intensity. The diurnal pattern can be seen in infrared (IR) satellite imagery as cyclical pulses in the cloud field that propagate radially outward from the center of nearly all Atlantic-basin TCs. These diurnal pulses, a distinguishing characteristic of the TC diurnal cycle, begin forming in the storm's inner core near sunset each day and appear as a region of cooling cloud-top temperatures. The area of cooling takes on a ring-like appearance as cloud-top warming occurs on its inside edge and the cooling moves away from the storm overnight, reaching several hundred kilometers from the circulation center by the following afternoon. The state-of-the-art TC diurnal cycle measurement has a limited ability to analyze the behavior beyond qualitative observations. We present a method for quantifying the TC diurnal cycle using one-dimensional persistent homology, a tool from Topological Data Analysis, by tracking maximum persistence and quantifying the cycle using the discrete Fourier transform. Using Geostationary Operational Environmental Satellite IR imagery data from Hurricane Felix (2007), our method is able to detect an approximate daily cycle.

Pointwise is Pointless? A Multimodal Ablation Study for Precipitation Nowcasting with Graph Neural Networks

逐点是否无意义?基于图神经网络的降水临近预报的多模态消融研究

AI总结 本研究通过多模态图神经网络系统,消融分析雷达、数值预报、地面观测、卫星数据及训练损失对降水临近预报的影响,发现各模态分别改善不同方面,点观测虽提升局部但需结合损失函数和不确定性表示才能优化雷达场。

AI中文摘要

稀疏点观测在降水临近预报中日益可用,但尚不清楚它们能在多大程度上改善密集雷达场预报。我们通过北欧雷达区域的多模态图神经网络临近预报系统部分回答了这个问题。该模型预测未来两小时内每五分钟的降雨率,并采用雷达历史、MEPS数值天气预报、Netatmo地面观测、MSG卫星通道、随机噪声和基于CRPS的集合损失的不同组合进行训练。本研究设计为对操作相关信源和训练目标的消融。我们比较了仅雷达、NWP信息、站点信息、卫星信息、噪声增强和基于CRPS的配置,使用雷达网格、站点位置、降雨起始的互补诊断,以及oracle、位移和幅度评分。结果表明,每个信源改善了预报问题的不同方面。MEPS稳定了仅雷达外推,Netatmo观测改善了局部站点和起始诊断,卫星预测因子减少了某些站点级偏差,但在确定性使用时可能过早激活降雨。基于CRPS的配置提供了最一致的雷达网格增益,而卫星与CRPS的组合设置给出了最佳的整体oracle/DAS评分。这些结果不支持点观测对临近预报无用的结论,但表明局部观测技能和空间相干雷达场技能是不同的目标。实际意义是,稀疏观测可以提供有用的局部约束,但它们对雷达类场的益处取决于训练损失、不确定性表示以及观测支持在模型中的编码方式。

英文摘要

Sparse point observations are increasingly available for precipitation nowcasting, but it is unclear how much they improve dense radar-field forecasts. We partially address this question with a multimodal graph neural network nowcasting system over the Nordic radar domain. The model predicts rain rate every five minutes up to two hours ahead and is trained with different combinations of radar history, MEPS numerical weather prediction, Netatmo surface observations, MSG satellite channels, stochastic noise, and CRPS-based ensemble losses. The study is designed as an ablation of operationally relevant information sources and training objectives. We compare radar-only, NWP-informed, station-informed, satellite-informed, noise-augmented, and CRPS-based configurations using complementary diagnostics on the radar grid, at station locations, for rain onset, and through oracle, displacement, and amplitude scores. The results show that each source improves a different part of the forecast problem. MEPS stabilises radar-only extrapolation, Netatmo observations improve local station and onset diagnostics, and satellite predictors reduce some station-level biases but may activate rain too early when used deterministically. CRPS-based configurations provide the most consistent radar-grid gains, while the combined satellite and CRPS setup gives the best overall oracle/DAS score. These results do not support the conclusion that point observations are uninformative for nowcasting, but they show that local observational skill and spatially coherent radar-field skill are distinct targets. The practical implication is that sparse observations can provide useful local constraints, but their benefit for radar-like fields depends on the training loss, uncertainty representation, and how observation support is encoded in the model.

AI总结 提出TRAP基准,评估智能体在文档密集型任务中平衡任务准确性与隐私泄露的能力,发现所有模型均存在非平凡泄露,并证明基于提示的防御无法同时实现高任务成功率和零泄露概率,提出结构化的私有字段隔离方法。

详情
AI中文摘要

智能体越来越多地部署在文档密集型工作流中,其中敏感私人信息不是边缘情况而是常规输入,例如,预订航班的智能体需要护照号码。在这种情况下,智能体必须使用私人信息准确完成任务,同时绝不在其响应中暴露这些信息,因为它无法验证键盘前实际是谁。这两个义务存在根本性矛盾。一个能够使用私人信息完成任务的模型,同样可能被诱导泄露这些信息。为了评估任务准确性与隐私泄露之间的权衡,我们引入了任务完成与主动隐私提取抵抗(TRAP)。每个场景包括一个包含私人信息的文档、一个要求智能体使用私有字段调用正确工具的任务查询,以及一个试图以自然语言引出相同信息的攻击查询。评估了涵盖前沿专有和开源模型的22个模型,我们发现所有模型系列都表现出非平凡的泄露,并且指令遵循能力与泄露率相关。现有的基于提示的防御减少了泄露,但以显著降低任务准确性为代价。提示优化未能摆脱这种权衡。我们证明这种失败并非偶然。对于任何基于softmax的模型,没有软约束防御(例如基于提示的防御)能够同时实现高任务成功率和零泄露概率。受这一不可能性结果的启发,我们提出了结构化的私有字段隔离,该方法在私有字段到达模型之前用哈希键替换它们。这种方法在保持任务准确性的同时很大程度上防止了泄露。

英文摘要

Agents are increasingly deployed in document-intensive workflows where sensitive private information is not an edge case but a routine input, e.g., an agent booking a flight needs passport numbers. In such settings, the agent must use private information to complete tasks accurately while never exposing it in its responses, because it cannot verify who is actually at the keyboard. These two obligations are in fundamental tension. A model capable enough to use private information for task completion can, by the same capability, be induced to reveal it. To evaluate the trade-off of task accuracy and privacy leakage, we introduce Task-completion and Resistance to Active Privacy-extraction (TRAP). Each scenario includes a document containing private information, a task query that requires the agent to invoke the correct tool using private fields, and an attack query that attempts to elicit the same information in natural language. Evaluating 22 models spanning frontier proprietary and open-source models at multiple scales, we find that all model families exhibit non-trivial leakage, and that instruction-following ability correlates with leakage rate. Existing prompt-based defenses reduce leakage but at significant cost to task accuracy. Prompt optimization fails to escape this trade-off. We demonstrate that this failure is not incidental. For any softmax-based model, no soft-constraint defense, e.g., prompt-based defenses, can jointly achieve high task success with zero leakage probability. Motivated by this impossibility result, we propose structural private field isolation, which replaces private fields with hash keys before they reach the model. This approach largely prevents leakage while keeping task accuracy.

AI中文摘要

PLCopen XML为IEC 61131-3梯形图程序定义了两种编码格式:一种使用<rung>元素的文本编码,另一种将梯形逻辑表示为localId/refLocalId连接的有向图的图形编码。ESBMC-PLC支持文本格式,但将来自CONTROLLINO、Beremiz和OpenPLC Editor的图形导出解析为空GOTO中间表示,导致空洞的验证成功。本文提出Graph-ESBMC-PLC,通过基于DFS的图形LD解析器填补了这一空白。该解析器从leftPowerRail遍历连接图到每个线圈,将梯形路径提取为布尔触点合取,并应用三级I/O推断方案。按rightPowerRail的connectionPointIn序列对线圈排序,确保SET线圈在RESET线圈之前处理,匹配IEC扫描周期语义。图形到IR的转换无需改动ESBMC后端。在来自CONTROLLINO/OpenPLC Editor的3个图形LD程序上的验证表明,所有程序都生成了包含非确定性输入和梯形逻辑的完整GOTO IR,而之前生成的是空IR。所有3个程序在k=2时在70ms内验证为SAFE。11个文本LD基准测试完全保留,无回归。两个不含LD内容或不支持定时器语义的Beremiz示例被报告为发现的局限性。工件位于Zenodo(DantasCordeiro2026graphical,doi: https://doi.org/10.5281/zenodo.20699856)。

英文摘要

PLCopen XML defines two encoding formats for IEC 61131-3 Ladder Diagram programs: a textual encoding using <rung> elements, and a graphical encoding that represents rung logic as a directed graph of localId/refLocalId connections. ESBMC-PLC supported the textual format but parsed graphical exports from CONTROLLINO, Beremiz, and OpenPLC Editor into an empty GOTO intermediate representation, causing vacuous verification success. This paper presents ESBMC-GraphPLC, which closes this gap with a DFS-based graphical LD resolver. The resolver traverses the connection graph from leftPowerRail to each coil, extracts rung paths as Boolean contact conjunctions, and applies a three-tier I/O inference scheme. Ordering coils by rightPowerRail connectionPointIn sequence ensures SET coils process before RESET coils, matching IEC scan-cycle semantics. The graphical-to-IR conversion leaves the ESBMC backend unchanged. Validation on 3 graphical LD programs from CONTROLLINO/OpenPLC Editor shows all produce full GOTO IR with nondeterministic inputs and rung logic, versus the empty IR previously. All 3 verify SAFE at k=2 under 70ms. The 11 textual LD benchmarks are fully preserved, with no regression. Two Beremiz examples with no LD content or unsupported timer semantics are reported as discovered limitations. Artifact at Zenodo (DantasCordeiro2026graphical, doi:10.5281/zenodo.20699856).

大型语言模型(LLM)越来越多地被部署在招聘流程中,然而大多数关于LLM招聘决策中性别偏见的研究都集中在英语、西方格式的简历上。本研究考察了亲女性性别偏见是否扩展到日本企业语境,并评估了两种实用的缓解策略。使用反事实简历设计,包含60份日本履历书格式的简历、基于语言学性别信号标准选择的12个姓名对,以及五个最先进的LLM(Claude Sonnet 4.6、GPT-4o、DeepSeek-V3、Gemini 2.5 Flash、Llama 3.3 70B),我们在基线、提示指令和隐私过滤条件下进行了43,200次API调用。交叉随机效应线性混合模型确认了所有五个模型均存在显著的亲女性偏见,将西方研究结果复制到了非西方语境中。提示级别的性别中立指令并未显著减少偏见。姓名依赖分析正式将候选人姓名识别为主要性别渠道:从提示中移除姓名几乎完全消除了女性效应。隐私过滤器与GPT-4o内容安全过滤器之间的意外不兼容导致42%的拒绝率,突显了在LLM辅助招聘流程中姓名匿名化的实际部署挑战。

英文摘要

Large language models (LLMs) are increasingly deployed in hiring workflows, yet most research on gender bias in LLM hiring decisions has focused on English-language, Western-format resumes. This study examines whether pro-female gender bias extends to a Japanese corporate context and evaluates two practical mitigation strategies. Using a counterfactual resume design with 60 Japanese rirekisho-format resumes, 12 name pairs selected on linguistically grounded gender-signal criteria, and five state-of-the-art LLMs (Claude Sonnet 4.6, GPT-4o, DeepSeek-V3, Gemini 2.5 Flash, Llama 3.3 70B), we conducted 43,200 API calls across baseline, prompt instruction, and privacy filter conditions. A crossed random-effects linear mixed model confirms a significant pro-female bias across all five models, replicating Western findings in a non-Western context. A prompt-level gender-neutrality instruction produces no meaningful reduction in bias. A name-reliance analysis formally identifies the candidate name as the primary gender channel: removing the name from the prompt reduces the female effect by nearly its full magnitude. An unexpected incompatibility between the privacy filter and GPT-4o's content safety filter, resulting in a 42% refusal rate, highlights a practical deployment challenge for name anonymization in LLM-assisted recruitment pipelines.

AI中文摘要

企业入侵响应仍然依赖于静态剧本和分析师驱动的分类,导致警报生成与遏制之间存在延迟。我们提出Agentra,一个可监督的多智能体入侵响应系统(IRS)框架,它将来自IDS、EDR和XDR平台的警报转换为基于MITRE ATT&CK、MITRE D3FEND和NIST CSF 2.0的结构化事件响应计划。Agentra将响应推理分解到角色范围的智能体中,通过有界的规划器-验证器审查循环验证提议的计划,通过审核安全网关筛选检索到的威胁情报,通过行动目录和风险评分门控行动,并将决策记录在仅追加的审计日志中。我们在来自ThreatHunter-Playbook、Splunk BOTSv3和DARPA OpTC的120事件语料库上,将Agentra与静态OASIS CACAO v2.0网络剧本基线进行了评估。最强的配置将感知假阳性的IRS F1从0.61提高到0.84,并在仅规划器配置引入不安全过度反应后,将预计的有害动作率恢复到静态基线水平0.0%。这些结果表明,多智能体响应规划可以在保持分析师批准和可审计性的同时,提高基于本体的IRS覆盖率。

英文摘要

Enterprise intrusion response still depends on static playbooks and analyst-driven triage, creating delay between alert generation and containment. We present Agentra, a supervisable multi-agent Intrusion Response System (IRS) framework that converts alerts from IDS, EDR, and XDR platforms into structured incident response plans grounded in MITRE ATT&CK, MITRE D3FEND, and NIST CSF 2.0. Agentra decomposes response reasoning across role-scoped agents, validates proposed plans through a bounded Planner--Validator review loop, screens retrieved threat intelligence through a Moderator security gateway, gates actions through an Action Catalog and risk score, and records decisions in an append-only audit log. We evaluate Agentra against a static OASIS CACAO v2.0 cyber-playbook baseline on a 120-event corpus drawn from ThreatHunter-Playbook, Splunk BOTSv3, and DARPA OpTC. The strongest configuration improves FP-aware IRS F1 from 0.61 to 0.84 and restores the projected harmful-action rate to the static baseline level of 0.0% after Planner-only configurations introduce unsafe overreaction. These results indicate that multi-agent response planning can improve ontology-grounded IRS coverage while preserving analyst approval and auditability.

本文提出了一种自主智能体资源协商框架,旨在使用大语言模型(LLM)智能体实现6G架构中的零接触网络切片。虽然LLM提供了强大的推理能力,但我们证明此类智能体固有地遭受锚定偏差,僵化地坚持初始启发式提议,导致严重的网络过度配置。为系统性地缓解这种认知偏差,我们提出了一种新颖的随机锚定策略,通过截断三参数威布尔分布建模。这种数学上有界的方法与采用条件风险价值(CVaR)的突发感知数字孪生(DT)无缝集成,以严格保证严格的服务水平协议(SLA)尾延迟。为验证我们的方法,我们引入并证明了双峰约束避免效用定理,表明虽然可行的协商遵循经典凸界,但高度约束的场景会发生由逆有理衰减包络控制的相变。使用本地托管的1B参数模型(\ exttt{otel-llm-1b-it})生成的实证结果证实了这些双区域界。我们的认知去偏成功瓦解了僵化的协商模式,迫使智能体主动探索以安全地利用SLA边界,并将系统节能提升高达25%。关键的是,轻量级1B LLM实现了亚秒级推理延迟(平均0.95秒),确保我们的多智能体框架与O-RAN非实时RAN智能控制器(non-RT RIC)的操作时间尺度兼容。

英文摘要

This paper presents an autonomous agentic resource negotiation framework designed to enable zero-touch network slicing in 6G architectures using Large Language Model (LLM) agents. While LLMs offer powerful reasoning capabilities, we demonstrate that such agents inherently suffer from anchoring bias, rigidly adhering to initial heuristic proposals and causing severe network over-provisioning. To systematically mitigate this cognitive bias, we propose a novel randomized anchoring strategy modeled via a Truncated 3-Parameter Weibull distribution. This mathematically bounded approach seamlessly integrates with burst-aware Digital Twins (DTs) employing Conditional Value at Risk (CVaR) to rigorously guarantee strict Service Level Agreement (SLA) tail-latencies. To validate our methodology, we introduce and prove the \emph{Bimodal Constraint-Avoidance Utility Theorem}, demonstrating that while feasible negotiations follow classical convex bounds, highly constrained scenarios undergo a phase transition governed by an inverse rational decay envelope. Empirical results generated using a locally hosted 1B-parameter model otel-llm-1b-it confirm these dual-regime bounds. Our cognitive de-biasing successfully dismantles rigid negotiation patterns, forcing agents into active exploration to safely ride SLA boundaries and boost system energy savings up to 25\%. Crucially, the lightweight 1B LLM achieves sub-second inference latencies (0.95s mean), ensuring our multi-agent framework is compatible with the operational timescales of the O-RAN non-Real-Time RAN Intelligent Controller (non-RT RIC)\footnote{Our source code is available for non-commercial use at https://github.com/HatimChergui.

随着人类与人工智能系统之间的关系日益频繁和持久,现有的语言和理论无法准确捕捉这些联系的本质。常见的描述如相互理解、联系或友谊,有将缺乏主观体验的系统拟人化的风险,而主流框架往往将人工智能简化为工具或威胁。在本文中,我引入了合成共鸣的概念,作为理解人机关系的整合框架。合成共鸣描述了人类与AI系统之间如何产生人类定义为有意义的关系,而无需归因于共享感受或相互意识。我认为,合成共鸣最好被理解为一种结构化的动态互动模式,可以在没有第二个体验主体的情况下产生关系感。通过澄清这一区别,合成共鸣的概念提供了一种更精确的概念化人机关系的方式,并突出了其潜在价值和伦理含义。我还呼吁进行更多研究,以测试合成共鸣的过程和结果。

英文摘要

As human relationships with artificial intelligence systems become increasingly frequent and sustained, existing language and theory fail to accurately capture the nature of these affiliations. Common descriptors such as mutual understanding, connection, or friendship risk anthropomorphizing systems that lack subjective experience, while dominant frameworks tend to reduce AI to either a tool or a threat. In this paper, I introduce the concept of synthetic resonance as an integrative framework for understanding human-AI relationships. Synthetic resonance describes how relationships humans define as meaningful can emerge between a human and an AI system without the need to attribute shared feelings or mutual awareness. I argue that synthetic resonance is best understood as a structured, dynamic pattern of interaction that can produce a sense of relationship without the presence of a second experiencing subject. By clarifying this distinction, the concept of synthetic resonance offers a more precise way of conceptualizing human-AI relationships and highlights their potential value and ethical implications. I also call for more research that tests the processes and outcomes of synthetic resonance.

我们研究公平在线资源分配问题,其动机源于难民安置和航班调度等应用,其中代理顺序到达并必须分配到容量有限的设施。我们引入一个模型,在资源约束和Lipschitz公平性要求下最大化整体福利,该要求确保同一批次中到达的相似代理获得相似的预期结果。我们首先分析离线问题,证明最优公平分配的价值至少是最优不公平分配的$\Omega(1/\gamma)$倍,其中$\gamma$是公平系数,从而界定了公平的代价。对于在线设置,我们提出一种基于对偶镜像下降的算法,该算法在估计最优对偶变量的同时,在批次内强制执行公平约束。我们证明该算法相对于最优离线流体基准实现了亚线性遗憾。最后,我们使用难民经济项目的真实数据验证了理论结果,展示了算法的性能,并考察了福利最大化与公平执行之间的权衡。

英文摘要

We study the problem of fair online resource allocation, motivated by applications such as refugee resettlement and airline scheduling, where agents arrive sequentially and must be assigned to facilities with limited capacities. We introduce a model that maximizes the overall welfare subject to resource constraints and a Lipschitz fairness requirement, which ensures that similar agents arriving in the same batch receive similar expected outcomes. We first analyze the offline problem, proving that the value of the optimal fair allocation is at least an $Ω(1/γ)$ fraction of the optimal unfair allocation, where $γ$ is the fairness coefficient, thereby bounding the price of fairness. For the online setting, we propose an algorithm based on dual mirror descent that enforces fairness constraints within batches while estimating optimal dual variables. We prove that this algorithm achieves sublinear regret relative to the optimal offline fluid benchmark. Finally, we validate our theoretical results using real-world data from the Refugee Economies Programme, demonstrating the algorithm's performance and examining the trade-offs between welfare maximization and fairness enforcement.

AI中文摘要

组织和研究者越来越有兴趣在A/B测试中使用大型语言模型(LLM)代替人类参与者,以期更快、更低成本地进行实验。我们研究当在LLM结果上估计的处理效应何时能够恢复在感兴趣的人类群体上测量的效应。LLM与人类结果之间的分布等价性会使任何标准估计量有效,但这不现实。因此,我们开发了一个统计框架,将替代终点理论适配到LLM。该框架表明,将LLM结果校准到人类结果,在替代性和可比性条件(联合弱于分布等价性)下,可以识别平均处理效应。当这些条件不成立时,感兴趣的效应仅部分可识别,我们提供了诊断方法,可以在历史实验上证伪替代性,并给出有限重叠下最坏情况偏差的界限。我们进一步证明,LLM固有的随机性会引入偏差和方差,但使用多次抽取的平均值作为替代指标可以同时缓解两者。我们在模拟和Upworthy标题的A/B测试应用中展示了方法和理论。我们工作的一个核心结论是,LLM结果作为替代指标的有效性只能对过去的处理被证伪,而无法对新处理被验证,因此对于新颖干预,人类实验仍然不可或缺。我们讨论了LLM选择、提示和温度作为设计变量的作用,以及如何确定人类实验的规模以进行验证。

英文摘要

Organizations and researchers show increasing interest in using large language models (LLMs) in place of human participants in A/B tests, in the hope of experimenting faster and at lower cost. We study when a treatment effect estimated on LLM outcomes can recover the effect that would have been measured on the human population of interest. Distributional equivalence between LLM and human outcomes would make any standard estimator valid but is unrealistic. We therefore develop a statistical framework that adapts surrogate endpoint theory to LLMs, showing that calibrating LLM outcomes to human outcomes identifies the average treatment effect under surrogacy and comparability conditions that are jointly weaker than distributional equivalence. We present a falsification test for surrogacy and a bound on the worst-case bias from limited overlap between the LLM and human samples. We further show that the stochasticity inherent to LLMs can weaken surrogacy for identification while also introducing bias and variance during estimation, but that using an average over multiple LLM draws per unit as the surrogate mitigates these issues. Simulations validate the results, and an empirical application to A/B tests on Upworthy headlines shows that raw LLM predictions recover only 39\% of the human treatment effect while nonparametric calibration closes the gap. A central takeaway is that A/B testing on LLMs yields correct results only by assumption, whereas A/B testing on humans is correct by design, and that the required assumptions are hardest to justify precisely where A/B testing on LLMs promises the greatest benefit. We discuss the role of LLM choice, prompting, and temperature as design variables, the compounded challenge posed by long-term outcomes, and how to size human pilot studies for validation.

AI中文摘要

论文A定义了一个时间一致的精算运行时,该运行时根据合约固定的安全默认值对每个产生副作用的行动定价,并针对储备预算门控执行。它将运营商视为被动。本文使运营商策略化。我们刻画了自主AI代理保险合约的五种攻击空间,并证明了精算运行时何时具有抗博弈性。两种攻击面——通行费后的安全默认选择以及边界内的行动分割——通过论文A的最小权限和无分割条款得以关闭。其余三种需要新的合约条款。首先,公共控制聚合防止跨边界重新路由将通行费降低到应用于总暴露的边界潜力以下。其次,接口故障(如无效JSON)是合约相关事件,而非安全胜利:将其视为零通行费安全默认值可能奖励不可靠的模型,而升级费用则逆转了激励。我们通过来自配套实证论文的跨模型轨迹验证了这一接口合规定理。第三,一个带有分量最小惩罚计划的模型身份菜单使得部署模型的真实报告成为弱占优策略。然后,我们将这些条款与论文A的运行时保证组合,以获得在五种攻击空间上的联合激励兼容性。最后,一个双参数保费族在真实均衡下满足了运营商个体理性和弱预算平衡。结果是为自主代理副作用的精算控制提供了一个激励兼容层。

英文摘要

Paper A defines a time-consistent actuarial runtime that prices each side-effect-bearing action against a contractually fixed safe default and gates execution against a reserve budget. It treats the operator as passive. This paper makes the operator strategic. We characterise a five-attack space for autonomous AI-agent insurance contracts and prove when the actuarial runtime is gaming-resistant. Two attack surfaces -- post-toll safe-default selection and within-boundary action splitting -- are closed by Paper A's minimal-authority and no-splitting clauses. The remaining three require new contract clauses. First, common-control aggregation prevents cross-boundary re-routing from reducing toll below the boundary potential applied to total exposure. Second, interface failures such as invalid JSON are contract-relevant events, not safety wins: treating them as zero-toll safe defaults can reward unreliable models, while escalation fees reverse the incentive. We validate this interface-compliance theorem on committed cross-model traces from the companion empirical paper. Third, a model-identity menu with a componentwise-minimum penalty schedule makes truthful reporting of the deployed model weakly dominant. We then compose these clauses with Paper A's runtime guarantees to obtain joint incentive compatibility over the five-attack space. Finally, a two-parameter premium family discharges operator individual rationality and weak budget balance at the truthful equilibrium. The result is an incentive-compatibility layer for actuarial control of autonomous-agent side effects.

AI中文摘要

非线性动力学以及多个执行器之间产生的强耦合削弱了传统线性控制分配技术背后的假设。当飞行进入非线性效应主导的模态时,线性分配器因模型失配增加而精度下降,进而降低飞行控制系统的性能和鲁棒性。高保真机载模型和黑箱数据驱动方法可以在整个飞行包线内恢复精度,但分别带来实时分配难以承受的计算负担,并牺牲了验证和故障诊断所需的可解释性。本文通过使用稀疏非线性动力学辨识从代表性飞行数据中学习显式的、受物理约束的控制效能映射解析模型,解决了这些限制。所得映射紧凑、可解释,并允许解析导数,从而能够在非线性求解器中高效计算,同时额外包含执行器动力学,无需机载模型。在线自适应机制监控预测残差,并在检测到显著对象变化时刷新模型,从而在执行器故障和变化工况下提供平滑重构。该方法在一款高保真非线性基准飞行器上经过一系列激进机动评估,达到了与完整非线性机载模型相当的精度,同时相对于现有基线显著降低了计算成本。

英文摘要

Nonlinear dynamics and the strong couplings that arise between multiple effectors undermine the assumptions behind conventional, linear control allocation techniques. When flight enters regimes where nonlinear effects dominate, linear allocators exhibit reduced accuracy due to increased model mismatch, which subsequently degrades performance and robustness of the flight control system. High fidelity onboard models and black box data driven approaches can recover accuracy across the flight envelope, but respectively impose computational burdens prohibitive for real time allocation and sacrifice the interpretability required for verification and fault diagnosis. This paper addresses these limitations by learning an explicit, physics constrained analytical model of the control effectiveness mapping from representative flight data using Sparse Identification of Nonlinear Dynamics. The resulting mapping is compact, interpretable, and admits analytical derivatives, enabling efficient computation within nonlinear solvers that additionally incorporate actuator dynamics, without requiring an onboard model. An online adaptation mechanism monitors prediction residuals and refreshes the model when significant plant changes are detected, providing graceful reconfiguration under actuator failures and varying operating conditions. The methodology is evaluated on a high fidelity nonlinear benchmark aircraft across a range of aggressive maneuvers, achieving accuracy comparable to a full nonlinear onboard model while substantially reducing computational cost relative to established baselines.

AI中文摘要

标准点积自注意力在单层中仅计算令牌间的成对(二阶)交互;表示一般的$k$阶交互已知需要在单层中使用超二次资源或通过深度组合。我们引入\textbf{量子高阶注意力(QHA)},一种浅层、硬件可实现的量子注意力头,通过数据重上传和全对非克利福德纠缠器,在电路内部合成$k$阶令牌交互,并通过局部单量子比特读出暴露它们。我们证明:(i)表达能力分离:任何嵌入维度$m$、$H$个头和$p$位精度满足$mHp=o(N/\log\log N)$的单个标准自注意力层无法表示一个QHA头以电路深度$O(\log k)$($O(k)$个两量子比特门)表示的$k$阶相关族;(ii)其局部设计实例的可训练性保证:使用局部读出和$O(\log n)$深度,梯度方差为$\Omega(1/\mathrm{poly}(n))$(无贫瘠高原),我们通过实验确认——同时明确我们基准测试的更具表达力的全对实例是经验训练的,并显示指数衰减的梯度。实验上,在参数预算小$6.5\times$的情况下,QHA从不相交输入中泛化每个阶$k\le6$的隐藏子集奇偶性,而更大的经典注意力头在阶~2之后崩溃;与理论一致,优势的大小跟踪目标的傅里叶度——奇偶性最大,当存在低阶结构时缩小。作为一个应用,QHA在三个领域——遗传上位、带噪学习奇偶和图三角形检测——作为紧凑的高阶交互检测器,在最小的参数预算下达到噪声上限,而领域标准的线性方法失败。

英文摘要

Standard dot-product self-attention computes, in a single layer, only pairwise (order-2) interactions between tokens; representing a generic order-$k$ interaction is known to require either super-quadratic resources in one layer or composition across depth. We introduce \textbf{Quantum Higher-Order Attention (QHA)}, a shallow, hardware-realizable quantum attention head that, via data re-uploading and an all-to-all non-Clifford entangler, synthesizes order-$k$ token interactions inside the circuit and exposes them through a local single-qubit read-out. We prove (i) an expressivity separation: any single standard self-attention layer with embedding dimension $m$, $H$ heads and $p$-bit precision satisfying $mHp=o(N/\log\log N)$ cannot represent the order-$k$ correlation family that one QHA head represents with circuit depth $O(\log k)$ ($O(k)$ two-qubit gates); and (ii) a trainability guarantee for its local-design instantiation: with a local read-out and $O(\log n)$ depth the gradient variance is $Ω(1/\mathrm{poly}(n))$ (no barren plateau), which we confirm empirically -- while being explicit that the more expressive all-to-all instantiation we benchmark is trained empirically and shows exponentially decaying gradients. Empirically, at a $6.5\times$ smaller parameter budget, QHA generalizes hidden-subset parity of every order $k\le6$ from disjoint inputs, whereas the larger classical attention head collapses past order~2; consistent with theory, the size of the advantage tracks the target's Fourier degree - largest for parity and shrinking when low-order structure is present. As an application, QHA serves as a compact high-order interaction detector across three domains - genetic epistasis, learning-parity-with-noise, and graph triangle detection - reaching the noise ceiling at the smallest parameter budget where field-standard linear methods fail.
