Convergence of iterates and improved rates for accelerated augmented Lagrangian methods for linearly constrained convex optimization

Xin He, Nan-Jing Huang, Yi-Bin Xiao +1

Motivated by an inertial primal-dual dynamical system with vanishing damping, we propose a class of accelerated augmented Lagrangian methods with Nesterov extrapolation parameters…

Trajectory convergence and $o (t^{- 2})$ rates for Nesterov accelerated primal-dual dynamics without Lipschitz gradient assumption

Xin He, Nan-Jing Huang, Yi-Bin Xiao +1

We consider the Nesterov accelerated primal-dual dynamical system \[ \begin{cases} \ddot{x}(t)+\dfracÎ±{t}\dot{x}(t) +\nabla f(x(t)) +A^\top\bigl(Î»(t)+Î¸t\dotÎ»(t)\bigr)+Î²A^\top(…

On the convergence of doubly stochastic Primal-Dual Hybrid Gradient Method

Yiheng Xiao, Huikang Liu

We study a block-structured class of convex-concave saddle-point problems in which both the primal and dual variables admit natural separable decompositions. Motivated by large-sca…
