A Fano-Style Accuracy Upper Bound for LLM Single-Pass Reasoning in Multi-Hop QA

ICLR 2026poster

Multi-Hop Question Answering (MHQA) requires integrating dispersed, interdependent evidence through sequential reasoning under noise. This task is challenging for LLMs as they have a finite per-pass output capacity, beyond which the integration of task-relevant evidence proves unreliable. Consequent…

Do LLMs “Feel”? Emotion Circuits Discovery and Control

ICML 2026poster

As the demand for emotional intelligence in large language models (LLMs) grows, a key challenge lies in understanding the internal mechanisms that give rise to emotional expression and in controlling emotions in generated text. This study addresses three core questions: (1) Do LLMs contain context-a…

The Cylindrical Representation Hypothesis for Language Model Steering

ICML 2026poster

Steering is a widely used technique for controlling large language models, yet its effects are often unstable and hard to predict. Existing theoretical accounts are largely based on the Linear Representation Hypothesis (LRH). While LRH assumes that concepts can be orthogonalized for lossless control…

Adversarial Cooperative Rationalization: The Risk of Spurious Correlations in Even Clean Datasets

ICML 2025poster

This study investigates the self-rationalization framework constructed with a cooperative game, where a generator initially extracts the most informative segment from raw input, and a subsequent predictor utilizes the selected subset for its input. The generator and predictor are trained collaborati…

DyFlow: Dynamic Workflow Framework for Agentic Reasoning

NeurIPS 2025poster

Agent systems based on large language models (LLMs) have shown great potential in complex reasoning tasks, but building efficient and generalizable workflows remains a major challenge. Most existing approaches rely on manually designed processes, which limits their adaptability across different task…

MedTrinity-25M: A Large-scale Multimodal Dataset with Multigranular Annotations for Medicine

ICLR 2025poster

This paper introduces MedTrinity-25M, a comprehensive, large-scale multimodal dataset for medicine, covering over 25 million images across 10 modalities with multigranular annotations for more than 65 diseases. These multigranular annotations encompass both global information, such as modality and o…

Shaping the Safety Boundaries: Understanding and Defending Against Jailbreaks in Large Language Models

ACL 2025long

Jailbreaking in Large Language Models (LLMs) is a major security concern as it can deceive LLMs into generating harmful text. However, understanding of how jailbreaking works remains limited, hindering the development of effective defense strategies. To address this issue, we conduct a large-scale a…

Under the Shadow of Babel: How Language Shapes Reasoning in LLMs

EMNLP 2025

Language is not only a tool for communication but also a medium for human cognition and reasoning. If, as linguistic relativity suggests, the structure of language shapes cognitive patterns, then large language models (LLMs) trained on human language may also internalize the habitual logical structu

Word Form Matters: LLMs’ Semantic Reconstruction under Typoglycemia

ACL 2025finding

Human readers can efficiently comprehend scrambled words, a phenomenon known as Typoglycemia, primarily by relying on word form; if word form alone is insufficient, they further utilize contextual cues for interpretation. While advanced large language models (LLMs) exhibit similar abilities, the und…
