PORTS: Preference-Optimized Retrievers for Tool Selection with Large Language Models

PORTS:用于大语言模型工具选择的偏好优化检索器

Lorenzo Molfetta, Giacomo Frisoni, Nicolò Monaldini, Gianluca Moro

机构 * Department of Computer Science and Engineering, University of Bologna(计算机科学与工程系,博洛尼亚大学)

AI总结 研究针对大语言模型工具选择中现有检索器与LLMs不一致问题,提出PORTS方法,利用受困惑度启发的偏好信号,通过优化相关性及施加对比语义损失微调检索器,经多实验验证其通用性及提高工具选择准确性的能力,且计算需求低便于推广。

Language Models Can Resolve Reference Compositionally, But It's Not Their Native Strength: The Case of the Personal Relation Task

语言模型可以组合性地解析指代,但这并非其天然优势:以个人关系任务为例

Bart Evelo, Meaghan Fowlie, Denis Paperno

AI总结 通过个人关系任务,比较人类与大型语言模型在外延任务(确定指称对象)和内涵任务(结构化表示意义)上的表现,发现人类更擅长外延任务而LLM更擅长内涵任务,表明缺乏指称基础是LLM模拟人类语言理解的关键缺失。

Decoding the Multimodal Mind: Generalizable Brain-to-Text Translation via Multimodal Alignment and Adaptive Routing

解码多模态思维:通过多模态对齐和自适应路由实现可泛化的脑到文本翻译

Chunyu Ye, Yunhao Zhang, Jingyuan Sun, Chong Li, Yang Zhao, Shaonan Wang

机构 * State Key Laboratory of Multimodal Artificial Intelligence System, Institute of Automation, Chinese Academy of Sciences(多模态人工智能系统国家重点实验室,中国科学院自动化研究所) School of Artificial Intelligence, University of Chinese Academy of Sciences(中国科学院大学人工智能学院) Department of Computer Science, The University of Manchester(曼彻斯特大学计算机科学系) Department of Language Science and Technology, Hong Kong Polytechnic University(香港理工大学语言科学与技术系)

AI总结 该研究针对脑机接口从人脑解码语言的挑战,提出利用多模态大语言模型和路由模块的统一框架,通过多模态对齐和自适应路由将脑信号与多模态语义空间对齐,在fMRI等数据集实验中性能领先,还扩展到EEG和MEG数据,为现实应用提供灵活方案。
