Sparse Oblique Decision Trees: A Tool to Understand and Manipulate Neural Net Features

no code implementations7 Apr 2021 Suryabhan Singh Hada, Miguel Á. Carreira-Perpiñán, Arman Zharmagambetov

The widespread deployment of deep nets in practical applications has lead to a growing desire to understand how and why such black-box methods perform prediction.

Counterfactual Explanations for Oblique Decision Trees: Exact, Efficient Algorithms

no code implementations1 Mar 2021 Miguel Á. Carreira-Perpiñán, Suryabhan Singh Hada

We consider counterfactual explanations, the problem of minimally adjusting features in a source input instance so that it is classified as a target class under a given classifier.

Sampling the "Inverse Set" of a Neuron: An Approach to Understanding Neural Nets

no code implementations27 Sep 2019 Suryabhan Singh Hada, Miguel Á. Carreira-Perpiñán

This inverse set is a complicated high dimensional object that we explore by an optimization-based sampling approach.
