Sample Where You Struggle: Sharpening Base Model Reasoning via Entropy-Guided Power Sampling

Researchers introduce Entropy-Guided Power Sampling (EGPS), a novel training-free sampling method that accelerates reasoning in base language models by targeting high-entropy decision points rather than uniformly sampling across sequences. The technique achieves up to 12.6x speedup on mathematical and coding benchmarks while maintaining or improving accuracy, addressing fundamental inefficiencies in existing MCMC sampling approaches.

Bayesian Inference of Nonlinear Malaria Dynamics in Ghana via an Ensemble Markov Chain Monte Carlo Sampler

Researchers developed a Bayesian machine learning framework to model malaria dynamics in Ghana using health facility data from 2014-2023, achieving 99.58% accuracy in capturing non-linear, age-specific disease patterns. The model forecasts a gradual resurgence in malaria cases through 2026, with projections ranging from 137,000-149,000 cases in children under five and 348,000-375,000 in older populations, enabling data-driven public health decision-making.
