Variance Reduction for Non-Log-Concave Sampling with Applications to Inverse Problems
M. Berk Sahin, Ahmet Ege Tanriverdi, Behzad Sharif +1
Sampling from high-dimensional, non-log-concave distributions with unnormalized densities is a fundamental challenge in machine learning, particularly when the exact gradient of th…

Zeroth-Order Non-Log-Concave Sampling with Variance Reduction and Applications to Inverse Problems
M. Berk Sahin, Behzad Sharif, Abolfazl Hashemi
Sampling from high-dimensional, non-log-concave distributions with unnormalized densities remains a fundamental challenge in machine learning, particularly in black-box settings wh…
