High-Dimensional Gaussian Sampling: A Review and a Unifying Approach Based on a Stochastic Proximal Point Algorithm
Autor: Maxime Vono, Nicolas Dobigeon, Pierre Chainais
Publikováno v: SIAM Review
SIAM Review, Society for Industrial and Applied Mathematics, In press, à paraître, pp.1-53
Efficient sampling from a high-dimensional Gaussian distribution is an old but high-stake issue. Vanilla Cholesky samplers imply a computational cost and memory requirements which can rapidly become prohibitive in high dimension. To tackle these issu
