HiPRAG: Hierarchical Process Rewards for Efficient Agentic Retrieval Augmented Generation

ICLR 2026poster

Agentic Retrieval-Augmented Generation (RAG) is a powerful technique for incorporating external information that Large Language Models (LLMs) lack, enabling better problem solving and question answering. However, suboptimal search behaviors exist widely, such as over-search (retrieving information a…

MMTok: Multimodal Coverage Maximization for Efficient Inference of VLMs

ICLR 2026poster

Vision-Language Models (VLMs) demonstrate impressive performance in understanding visual content with language instruction by converting visual inputs to vision tokens. However, redundancy in vision tokens results in the degenerated inference efficiency of VLMs. While many algorithms have been propo…

CBT-Bench: Evaluating Large Language Models on Assisting Cognitive Behavior Therapy

NAACL 2025long

There is a significant gap between patient needs and available mental health support today. In this paper, we aim to thoroughly examine the potential of using Large Language Models (LLMs) to assist professional psychotherapy. To this end, we propose a new benchmark, CBT-Bench, for the systematic eva…

IDEA: Enhancing the Rule Learning Ability of Large Language Model Agent through Induction, Deduction, and Abduction

ACL 2025finding

While large language models (LLMs) have been thoroughly evaluated for deductive and inductive reasoning, their proficiency in holistic rule learning in interactive environments remains less explored. We introduce RULEARN, a novel benchmark to assess the rule-learning abilities of LLM agents in inter…

LMR-BENCH: Evaluating LLM Agent’s Ability on Reproducing Language Modeling Research

EMNLP 2025

Large language model (LLM) agents have demonstrated remarkable potential in advancing scientific discovery. However, their capability in the fundamental yet crucial task of reproducing code from research papers, especially in the NLP domain, remains underexplored. This task includes unique complex r

Search Wisely: Mitigating Sub-optimal Agentic Searches By Reducing Uncertainty

EMNLP 2025

Agentic Retrieval-Augmented Generation (RAG) systems enhance Large Language Models (LLMs) by enabling dynamic, multi-step reasoning and information retrieval. However, these systems often exhibit sub-optimal search behaviors like over-search (retrieving redundant information) and under-search (faili

Emotion Recognition in Conversation from Variable-Length Context

ICASSP 2023accepted

Existing approaches to Emotion Recognition in Conversation (ERC) use a fixed context window to recognize speakers’ emotion, which may lead to either scantiness of key context or interference of redundant context. In response, we explore the benefits of variable-length context and propose a more effe…

SafeConv: Explaining and Correcting Conversational Unsafe Behavior

ACL 2023long

One of the main challenges open-domain end-to-end dialogue systems, or chatbots, face is the prevalence of unsafe behavior, such as toxic languages and harmful suggestions. However, existing dialogue datasets do not provide enough annotation to explain and correct such unsafe behavior. In this work,…
