Mathesis: Towards Formal Theorem Proving from Natural Languages

ICLR 2026poster

Recent advances in large language models (LLMs) show strong promise for formal reasoning. However, most LLM-based theorem provers remain constrained by the need for expert-written formal statements as inputs, limiting their applicability to real-world problems expressed in natural language. We addre…

Augmenting Math Word Problems via Iterative Question Composing

AAAI 2025technical

Despite the advancements in large language models (LLMs) for mathematical reasoning, solving competition-level math problems remains a significant challenge, especially for open-source LLMs without external tools. We introduce the MMIQC dataset, comprising a mixture of processed web data and synthet…

ProofAug: Efficient Neural Theorem Proving via Fine-grained Proof Structure Analysis

ICML 2025poster

The synergy between deep learning models and traditional automation tools, such as built-in tactics of the proof assistant and off-the-shelf automated theorem provers, plays a crucial role in developing robust and efficient neural theorem provers~(NTPs). However, for proof synthesis with LLMs, previ…
