An adaptive heavy ball method for ill-posed inverse problems
Qinian Jin, Qin Huang
In this paper we consider ill-posed inverse problems, both linear and nonlinear, by a heavy ball method in which a strongly convex regularization function is incorporated to detect…

Stochastic variance reduced gradient method for linear ill-posed inverse problems
Qinian Jin, Liuhong Chen
In this paper we apply the stochastic variance reduced gradient (SVRG) method, which is a popular variance reduction method in optimization for accelerating the stochastic gradient…

On convergence rates of proximal alternating direction method of multipliers
Qinian Jin
In this paper we consider from two different aspects the proximal alternating direction method of multipliers (ADMM) in Hilbert spaces. We first consider the application of the pro…
