Greedy Step Averaging: A parameter-free stochastic optimization method

11 Nov 2016 Xiatian Zhang Fan Yao Yongjun Tian

In this paper we present the greedy step averaging(GSA) method, a parameter-free stochastic optimization algorithm for a variety of machine learning problems. As a gradient-based optimization method, GSA makes use of the information from the minimizer of a single sample's loss function, and takes average strategy to calculate reasonable learning rate sequence...
