Albert S. Berahas, Raghu Bollapragada, Nitish Shirish Keskar +1
Methods for distributed optimization have received significant attention in recent years owing to their wide applicability in various domains. A distributed optimization method typ…
A Robust Multi-Batch L-BFGS Method for Machine Learning
Albert S. Berahas, Martin Takáč
This paper describes an implementation of the L-BFGS method designed to deal with two adversarial situations. The first occurs in distributed computing environments where some of t…
An Investigation of Newton-Sketch and Subsampled Newton Methods
Albert S. Berahas, Raghu Bollapragada, Jorge Nocedal
Sketching, a dimensionality reduction technique, has received much attention in the statistics community. In this paper, we study sketching in the context of Newton's method for so…
