Magenta: Closing the Loop Between Mathematical Reasoning and Lean Verification

Joshua Ong Jun Leang, Haonan Li, Zheng Zhao +7

Most of mathematical knowledge has been communicated through so-called informal use of mathematics and natural language. With large language models (LLMs) being highly adept in usi…

Pythagoras-Prover: Advancing Efficient Formal Proving via Augmented Lean Formalisation

Joshua Ong Jun Leang, Zheng Zhao, Mihaela Cătălina Stoian +5

Modern Lean theorem provers achieve strong performance only with substantial training and inference compute, driven in part by scarce verified proof data and the long reasoning tra…

CoLVR: Enhancing Exploratory Latent Visual Reasoning via Contrastive Optimization

Ziyang Ding, Linjian Meng, Yiming Wu +3

Due to the potential for exploratory reasoning of Latent Visual Reasoning, recent works tend to enable MLLMs (Multimodal Large Language Models) to perform visual reasoning by propa…

Training with Harnesses: On-Policy Harness Self-Distillation for Complex Reasoning

Zhengyang Zhao, Lu Ma, Wentao Zhang

Inference-time harnesses substantially improve large language models on complex reasoning tasks. However, the intrinsic capabilities of the underlying model remain unchanged by the…

CodeCircuit: Toward Inferring LLM-Generated Code Correctness via Attribution Graphs

Yicheng He, Zheng Zhao, Zhou Kaiyu +3

Current paradigms for code verification rely heavily on external mechanisms-such as execution-based unit tests or auxiliary LLM judges-which are often labor-intensive or limited by…

GIFT: Reconciling Post-Training Objectives via Variational Finite-Temperature Gibbs Initialization

Zhengyang Zhao, Lu Ma, Yizhen Jiang +7

The prevailing post-training paradigm for Large Reasoning Models (LRMs)---Supervised Fine-Tuning (SFT) followed by Reinforcement Learning (RL)-suffers from an intrinsic optimizatio…
