Discrepancy Ratio: Evaluating Model Performance When Even Experts Disagree on the Truth

ICLR 2020poster

In most machine learning tasks unambiguous ground truth labels can easily be acquired. However, this luxury is often not afforded to many high-stakes, real-world scenarios such as medical image interpretation, where even expert human annotators typically exhibit very high levels of disagreement with…

Defense-GAN: Protecting Classifiers Against Adversarial Attacks Using Generative Models

ICLR 2018poster

In recent years, deep neural network approaches have been widely adopted for machine learning tasks, including classification. However, they were shown to be vulnerable to adversarial perturbations: carefully crafted small perturbations can cause misclassification of legitimate images. We propose De…

ExplainGAN: Model Explanation via Decision Boundary Crossing Transformations

ECCV 2018poster

We introduce a new method for interpreting computer vision models: visually perceptible, decision-boundary crossing transformations. Our goal is to answer a simple question: why did a model classify an image as being of class A instead of class B? Existing approaches to model interpretation, includi…
