The Open Proof Corpus: A Large-Scale Study of LLM-Generated Mathematical Proofs

ICLR 2026poster

In recent months, large language models (LLMs) have made significant progress in mathematical proof generation, but further advancement is hindered by the lack of a large-scale, high-quality dataset of human-evaluated proofs. While expensive to create, such a dataset is essential for driving improve…

GRAIN: Exact Graph Reconstruction from Gradients

ICLR 2025poster

Federated learning claims to enable collaborative model training among multiple clients with data privacy by transmitting gradient updates instead of the actual client data. However, recent studies have shown the client privacy is still at risk due to the, so called, gradient inversion attacks which…

MathArena: Evaluating LLMs on Uncontaminated Math Competitions

NeurIPS 2025poster

The rapid advancement of reasoning capabilities in large language models (LLMs) has led to notable improvements on mathematical benchmarks. However, many of the most commonly used evaluation datasets (e.g., AIME 2024) are widely available online, making it difficult to disentangle genuine reasoning…

MathConstruct: Challenging LLM Reasoning with Constructive Proofs

ICML 2025poster

While Large Language Models (LLMs) demonstrate impressive performance in mathematics, existing math benchmarks come with significant limitations. Many focus on problems with fixed ground-truth answers, and are often saturated due to problem simplicity or the viability of guessing or memorization. Cr…

DAGER: Exact Gradient Inversion for Large Language Models

NeurIPS 2024poster

Federated learning works by aggregating locally computed gradients from multiple clients, thus enabling collaborative training without sharing private client data. However, prior work has shown that the data can actually be recovered by the server using so-called gradient inversion attacks. While th…
