Newton-ADMM: A Distributed GPU-Accelerated Optimizer for Multiclass Classification Problems

1 code implementation18 Jul 2018 Chih-Hao Fang, Sudhir B. Kylasa, Fred Roosta, Michael W. Mahoney, Ananth Grama

First-order optimization methods, such as stochastic gradient descent (SGD) and its variants, are widely used in machine learning applications due to their simplicity and low per-iteration costs.

GPU Accelerated Sub-Sampled Newton's Method

no code implementations26 Feb 2018 Sudhir B. Kylasa, Farbod Roosta-Khorasani, Michael W. Mahoney, Ananth Grama

In particular, in convex settings, we consider variants of classical Newton\textsf{'}s method in which the Hessian and/or the gradient are randomly sub-sampled.
