Task Embedded Coordinate Update: A Realizable Framework for Multivariate Non-convex Optimization
Yiyang Wang, Risheng Liu, Long Ma +1
We in this paper propose a realizable framework TECU, which embeds task-specific strategies into update schemes of coordinate descent, for optimizing multivariate non-convex proble…
Learning Converged Propagations with Deep Prior Ensemble for Image Enhancement
Risheng Liu, Long Ma, Yiyang Wang +1
Enhancing visual qualities of images plays very important roles in various vision and learning applications. In the past few years, both knowledge-driven maximum a posterior (MAP)…
A FE-inexact heterogeneous ADMM for Elliptic Optimal Control Problems with {}-Control Cost
Xiaoliang Song, Bo Yu, Yiyang Wang +1
Elliptic PDE-constrained optimal control problems with -control cost (-EOCP) are considered. To solve -EOCP, the primal-dual active set (PDAS) method, which is a spe…
An Optimization Framework with Flexible Inexact Inner Iterations for Nonconvex and Nonsmooth Programming
Yiyang Wang, Risheng Liu, Xiaoliang Song +1
In recent years, numerous vision and learning tasks have been (re)formulated as nonconvex and nonsmooth programmings(NNPs). Although some algorithms have been proposed for particul…
Sparse Coding and Counting for Robust Visual Tracking
Risheng Liu, Jing Wang, Yiyang Wang +2
In this paper, we propose a novel sparse coding and counting method under Bayesian framwork for visual tracking. In contrast to existing methods, the proposed method employs the co…
