Topic | Rapid Convergence of Unadjusted Langevin Algorithm (ULA) by Vempala and Wibisono. | ||
Contents | 높은 고차원의 Target 확율분포 p=Exp(-f) 부터 데이터를 샘플링하는 난해한 문제를 Optimization Problem 관점에서 접근 하여 , p가 log-Sobolev Inequality 또는 Poincare' Inequality를 만족 할 때 Langevin Dynamics( Ito Diffusion)이 Kullback-Liebler Divergence, Renyi Divergence, Warsserstein Distance를 Minimizing하는 continuous time optimal generating 하는 SDE이고 discrete-time generating algorithm(ULA)의 수렴성을 증명하였다. 따라서 ULA가 이론적으로 근사적으로 최적화 된 샘플생성 알고리즘임을 볼수 있다. |
