Leader Stochastic Gradient Descent for Distributed Training of Deep Learning Models: Extension

1 code implementation NeurIPS 2019 Yunfei Teng, Wenbo Gao, Francois Chalus, Anna Choromanska, Donald Goldfarb, Adrian Weller

Finally, we implement an asynchronous version of our algorithm and extend it to the multi-leader setting, where we form groups of workers, each represented by its own local leader (the best performer in a group), and update each worker with a corrective direction comprised of two attractive forces: one to the local, and one to the global leader (the best performer among all workers).

Stochastic Adaptive Quasi-Newton Methods for Minimizing Expected Values

no code implementations ICML 2017 Chaoxu Zhou, Wenbo Gao, Donald Goldfarb

We propose a novel class of stochastic, adaptive methods for minimizing self-concordant functions which can be expressed as an expected value.
