New method enhances generative sampling for lattice field theory
Researchers have developed a novel method called Operator-Guided Model Reduction to improve generative sampling in lattice field theory. This technique projects trained neural network velocities onto vector fields deriv…

New proofs advance Dikin walks mixing time analysis for sampling
Researchers have developed new methods to analyze the mixing time of weighted Dikin walks, which are used for sampling from exponential distributions on polytopes and truncated positive-semidefinite (PSD) cones. The fir…
