Convergence Rates of Inertial Splitting Schemes for Nonconvex Composite Optimization
Patrick R. Johnstone, Pierre Moulin
We study the convergence properties of a general inertial first-order proximal splitting algorithm for solving nonconvex nonsmooth optimization problems. Using the Kurdyka--Łojazie…
On Information-Theoretic Characterizations of Markov Random Fields and Subfields
Raymond W. Yeung, Ali Al-Bashabsheh, Chao Chen +2
Let form a Markov random field (MRF) represented by an undirected graph , and be a subset of . We determine the smallest graph that can always rep…
Variable-Length Hashing
Honghai Yu, Pierre Moulin, Hong Wei Ng +1
Hashing has emerged as a popular technique for large-scale similarity search. Most learning-based hashing methods generate compact yet correlated hash codes. However, this redundan…
Local and Global Convergence of a General Inertial Proximal Splitting Scheme
Patrick R. Johnstone, Pierre Moulin
This paper is concerned with convex composite minimization problems in a Hilbert space. In these problems, the objective is the sum of two closed, proper, and convex functions wher…
