EvolProver: Advancing Automated theorem proving by Evolving Formalized Problems via Symmetry and Difficulty

ICLR 2026poster

Large Language Models (LLMs) for formal theorem proving have shown significant promise, yet they often lack generalizability and are fragile to even minor transformations of problem statements. To address this limitation, we introduce a novel data augmentation pipeline designed to enhance model robu…

Pushing the Boundaries of Natural Reasoning: Interleaved Bonus from Formal-Logic Verification

ICML 2026poster

Large Language Models (LLMs) show remarkable capabilities, yet their stochastic next-token prediction creates logical inconsistencies and reward hacking that formal symbolic systems avoid. To bridge this gap, we introduce a formal logic verification-guided framework that dynamically interleaves form…

CodeHalu: Investigating Code Hallucinations in LLMs via Execution-based Verification

AAAI 2025technical

Large Language Models (LLMs) have made significant progress in code generation, offering developers groundbreaking automated programming support. However, LLMs often generate code that is syntactically correct and even semantically plausible, but may not execute as expected or fulfill specified requ…

CodeJudge-Eval: Can Large Language Models be Good Judges in Code Understanding?

COLING 2025main

Recent advancements in large language models (LLMs) have showcased impressive code generation capabilities, primarily evaluated through language-to-code benchmarks. However, these benchmarks may not fully capture a model’s code understanding abilities. We introduce CodeJudge-Eval (CJ-Eval), a novel…

MM-CRITIC: A Holistic Evaluation of Large Multimodal Models as Multimodal Critique

EMNLP 2025

The ability of critique is vital for models to self-improve and serve as reliable AI assistants. While extensively studied in language-only settings, multimodal critique of Large Multimodal Models (LMMs) remains underexplored despite their growing capabilities in tasks like captioning and visual rea

Token Alignment via Character Matching for Subword Completion

ACL 2024findings

Generative models, widely utilized in various applications, can often struggle with prompts corresponding to partial tokens. This struggle stems from tokenization, where partial tokens fall out of distribution during inference, leading to incorrect or nonsensical outputs. This paper examines a techn…
