Variable Metric Composite Proximal Alternating Linearized Minimization for Nonconvex Nonsmooth Optimization
Maryam Yashtini
In this paper we propose a proximal algorithm for minimizing an objective function of two block variables consisting of three terms: 1) a smooth function, 2) a nonsmooth function w…
Counting Objects by Diffused Index: geometry-free and training-free approach
Mengyi Tang, Maryam Yashtini, Sung Ha Kang
Counting objects is a fundamental but challenging problem. In this paper, we propose diffusion-based, geometry-free, and learning-free methodologies to count the number of objects…
Convergence Analysis of A Proximal Linearized ADMM Algorithm for Nonconvex Nonsmooth Optimization
Maryam Yashtini
In this paper, we consider a proximal linearized alternating direction method of multipliers (PL-ADMM) for solving linearly constrained nonconvex and possibly nonsmooth optimizatio…
Multi-Block Nonconvex Nonsmooth Proximal ADMM: Convergence and Rates under Kurdyka-Łojasiewicz Property
Maryam Yashtini
In this paper, we consider a multi-block generalized alternating direction method of multiplier (GADMM) algorithm for minimizing a linearly constrained separable nonconvex and poss…
