LoRi: Low-Rank Distillation for Implicit Reasoning

Ryan Solgi, Jiayi Tian, Zheng Zhang

Implicit chain-of-thought (iCoT) methods aim to internalize reasoning in large language models, but often underperform explicit CoT prompting. We empirically find that hidden-state…

Listening with the Eyes: Benchmarking Egocentric Co-Speech Grounding across Space and Time

Weijie Zhou, Xuantang Xiong, Zhenlin Hu +6

In situated collaboration, speakers often use intentionally underspecified deictic commands (e.g., ``pass me \textit{that}''), whose referent becomes identifiable only by aligning…

Learning from Mistakes: Negative Reasoning Samples Enhance Out-of-Domain Generalization

Xueyun Tian, Minghua Ma, Bingbing Xu +6

Supervised fine-tuning (SFT) on chain-of-thought (CoT) trajectories demonstrations is a common approach for enabling reasoning in large language models. Standard practices typicall…

ESearch-R1: Learning Cost-Aware MLLM Agents for Interactive Embodied Search via Reinforcement Learning

Weijie Zhou, Xuangtang Xiong, Ye Tian +8

Multimodal Large Language Models (MLLMs) have empowered embodied agents with remarkable capabilities in planning and reasoning. However, when facing ambiguous natural language inst…
