Explanations based on the Missing: Towards Contrastive Explanations with Pertinent Negatives

NeurIPS 2018poster

In this paper we propose a novel method that provides contrastive explanations justifying the classification of an input by a black box classifier such as a deep neural network. Given an input we find what should be minimally and sufficiently present (viz. important object pixels in an image) to jus…

Zeroth-Order Stochastic Variance Reduction for Nonconvex Optimization

NeurIPS 2018poster

As application demands for zeroth-order (gradient-free) optimization accelerate, the need for variance reduced and faster converging approaches is also intensifying. This paper addresses these challenges by presenting: a) a comprehensive theoretical analysis of variance reduced zeroth-order (ZO) op…
