What happened

Collection of new stat-ML papers (arXiv 2026-04-27) introducing methods across bandits, sampling, kernel approximation, ensemble uncertainty, federated geometry-aware networks, explainability for dynamic fields, mixed-membership clustering, customer-revenue forecasting, and audits of LLM probabilistic sampling. Highlights include: (1) concave-utility multi-armed bandits optimized via influence-function gradients and entropic mirror-ascent; (2) pliable rejection sampling (PRS) learning proposals with kernel estimators and acceptance guarantees; (3) SQUEAK, an efficient unnormalized RLS-based Ny
