The Geometry of Reasoning: Flowing Logics in Representation Space

ICLR 2026poster

We study how large language models (LLMs) “think” through their representation space. We propose a novel geometric framework that models an LLM’s reasoning as flows—embedding trajectories evolving where logic goes. We disentangle logical structure from semantics by employing the same natural deduc…

ChemAgent: Self-updating Memories in Large Language Models Improves Chemical Reasoning

ICLR 2025poster

Chemical reasoning usually involves complex, multi-step processes that demand precise calculations, where even minor errors can lead to cascading failures. Furthermore, large language models (LLMs) encounter difficulties handling domain-specific formulas, executing reasoning steps accurately, and in…

DAMON: A Dialogue-Aware MCTS Framework for Jailbreaking Large Language Models

EMNLP 2025

While large language models (LLMs) demonstrate remarkable capabilities across a wide range of tasks, they remain vulnerable to generating outputs that are potentially harmful. Red teaming, which involves crafting adversarial inputs to expose vulnerabilities, is a widely adopted approach for evaluati

DSGram: Dynamic Weighting Sub-Metrics for Grammatical Error Correction in the Era of Large Language Models

AAAI 2025technical

Evaluating the performance of Grammatical Error Correction (GEC) models has become increasingly challenging, as large language model (LLM)-based GEC systems often produce corrections that diverge from provided gold references. This discrepancy undermines the reliability of traditional reference-base…

Evaluating Self-Generated Documents for Enhancing Retrieval-Augmented Generation with Large Language Models

NAACL 2025findings

The integration of documents generated by LLMs themselves (Self-Docs) alongside retrieved documents has emerged as a promising strategy for retrieval-augmented generation systems. However, previous research primarily focuses on optimizing the use of Self-Docs, with their inherent properties remainin…

Gödel Agent: A Self-Referential Agent Framework for Recursively Self-Improvement

ACL 2025long

The rapid advancement of large language models (LLMs) has significantly enhanced the capabilities of agents across various tasks. However, existing agentic systems, whether based on fixed pipeline algorithms or pre-defined meta-learning frameworks, cannot search the whole agent design space due to t…

Contextual Modeling for Document-level ASR Error Correction

COLING 2024main

Contextual information, including the sentences in the same document and in other documents of the dataset, plays a crucial role in improving the accuracy of document-level ASR Error Correction (AEC), while most previous works ignore this. In this paper, we propose a context-aware method that utiliz…

History Matters: Temporal Knowledge Editing in Large Language Model

AAAI 2024technical

The imperative task of revising or updating the knowledge stored within large language models arises from two distinct sources: intrinsic errors inherent in the model which should be corrected and outdated knowledge due to external shifts in the real world which should be updated. Prevailing efforts…

Themis: A Reference-free NLG Evaluation Language Model with Flexibility and Interpretability

EMNLP 2024main

The evaluation of natural language generation (NLG) tasks is a significant and longstanding research area. With the recent emergence of powerful large language models (LLMs), some studies have turned to LLM-based automatic evaluation methods, which demonstrate great potential to become a new evaluat…
