Frameworks & Tools

A new arXiv paper proposes measuring non-Gaussianity with the squared Wasserstein distance to a standard Gaussian. The resulting OT-ICA algorithm aims to replace common proxy contrasts used in classical ICA.

A new arXiv paper improves the theoretical mixing bound for Dikin walks on polytopes. Using a scaled Lee–Sidford metric, the author proves a d^2.25 warm-start mixing bound for exponential sampling.

PyTorch-Triton 3.7 introduces Triton Plugin Extensions, a runtime mechanism for loading compiler passes, MLIR dialects, and DSL extensions without forking Triton. Meta’s TLX is the first major beneficiary, enabling lower-level GPU kernel control in stock Triton.

A new arXiv paper proposes an efficient Newton-type algorithm for nonnegative matrix factorization with Kullback-Leibler divergence. Instead of relying on separable majorants, the method builds on a second-order Taylor approximation and a generalized HALS solver.

A new arXiv paper introduces Relevance-Aware Rule, a framework for detecting and deleting irrelevant conditions in decision-tree rules. Instead of pruning blindly, it checks whether removing a condition would undermine prediction reliability.

NodeImport reframes class-imbalanced node classification as a question of which nodes actually improve unbiased performance. The framework filters labeled, unlabeled, and synthetic nodes using an importance signal derived from a balanced meta-set.
