arXiv:2606.14867v1 Announce Type: new Abstract: Proof autoformalization aims to translate a mathematical informal proof written in natural language into a formal proof in a formal language such as Lean~4. Several works have developed LLM-based models for proof autoformalization. However, existing evaluations have typically focused on translating well-formed informal proofs from curated datasets. We argue that a robust proof autoformalizer must remain faithful even for informal proofs that diverge from these idealized ones, and we present the first study on the robustness of proof autoformaliza
The proliferation of LLMs makes their application to complex tasks like mathematical proof autoformalization a natural next step, while also highlighting the critical need for robustness testing.
Improving the robustness of AI in critical reasoning tasks like proof autoformalization is crucial for its adoption in high-stakes fields and for building trust in AI capabilities.
This research shifts the focus from merely demonstrating AI's ability to autoformalize proofs to rigorously evaluating its reliability under varied, less-than-ideal conditions.
