Beyond " I Don’t Know": Evaluating LLM Self-Awareness in Discriminating Data and Model Uncertainty

Jingyi Ren · Ante Wang · Yunghwei Lai · Xiaolong Wang · Linlu Gong · Weitao Li · Weizhi Ma · Yang Liu

摘要

Reliable Large Language Models (LLMs) should abstain when confidence is insufficient. However, prior studies often treat refusal as a generic "I don’t know”, failing to distinguish input-level ambiguity (data uncertainty) from capability limitations (model uncertainty). This lack of distinction l...

UR ^2 : Unify RAG and Reasoning through Reinforcement Learning

Weitao Li · Boran Xiang · Xiaolong Wang · Jingyi Ren · Ante Wang · Zhinan Gou · Weizhi Ma · Yang Liu

摘要

Large Language Models (LLMs) have shown strong capabilities through two complementary paradigms: Retrieval-Augmented Generation (RAG) for knowledge grounding and Reinforcement Learning from Verifiable Rewards (RLVR) for complex reasoning. However, existing attempts to unify these paradigms remain...

T hera A gent: Self-Improving Therapeutic Agent for Precise and Comprehensive Treatment Planning

Junkai Li · Yunghwei Lai · Tianyi Zhu · Zheng Long Lee · Weizhi Ma · Yang Liu

摘要

Formulating a treatment plan is inherently a complex reasoning and refinement task rather than a simple generation problem. However, existing large language models (LLMs) mainly rely on one-shot output without explicit verification, which may result in rough, incomplete, and potentially unsafe tr...

Understanding Internal Representations of Recommendation Models with Sparse Autoencoders

Jiayin Wang · Xiaoyu Zhang · Weizhi Ma · Zhiqiang Guo · Min Zhang

摘要

Recommendation model interpretation aims to reveal the relationships between inputs, model internal representations, and outputs to enhance the transparency, interpretability, and trustworthiness of recommendation systems. However, the inherent complexity and opacity of deep learning models pose...
