Linear Convergence of Accelerated Stochastic Gradient Descent for Nonconvex Nonsmooth Optimization

26 Apr 2017Feihu HuangSongcan Chen

In this paper, we study the stochastic gradient descent (SGD) method for the nonconvex nonsmooth optimization, and propose an accelerated SGD method by combining the variance reduction technique with Nesterov's extrapolation technique. Moreover, based on the local error bound condition, we establish the linear convergence of our method to obtain a stationary point of the nonconvex optimization... (read more)
