Two new research papers propose novel ensemble sampling techniques to improve the efficiency and accuracy of model exploration in machine learning. The first paper, "Linear Ensemble Sampling with Smaller Ensembles," introduces an algorithm that refreshes ensembles less frequently by monitoring changes in the Gram matrix, achieving state-of-the-art regret bounds with smaller ensemble sizes. The second paper, "Quenched Ensemble Sampling," presents a method that generalizes hard energy constraints to repulsive potentials, enabling more robust sampling across phase transitions and improving applications in Bayesian neural networks and lattice field theory.
