Randomized SVD Approximations for Spectral Co-Clustering of Word-Document Matrices

Spectral co-clustering is a useful tool for discovering latent structure in word-document matrices, but its reliance on singular value decomposition (SVD) can make standard formulations expensive on high-dimensional data. This paper presents two randomized approximations for normalized spectral co-clustering of biparti...

TREAT: Evaluating Access to Formal Knowledge across Equivalent Mathematical Representations

TREAT is introduced, a benchmark for evaluating whether large language models can recover known theorem identities from equivalence-preserving formula-level transformations, and provides a controlled testbed for evaluating representation-robust access to formal knowledge.

Beyond the Answer Key: Robustness Evaluation of Large Language Models for Step-Level Mathematical Verification

Evaluating state-of-the-art open LLMs reveals a significant robustness gap, and shows that reliable process-level verification remains challenging, and evaluator robustness should be measured separately from solver accuracy, even in a simple algebraic domain with exact ground truth.
