Augmentation by Counterfactual Explanation -- Fixing an Overconfident Classifier

no code implementations21 Oct 2022 Sumedha Singla, Nihal Murali, Forough Arabshahi, Sofia Triantafyllou, Kayhan Batmanghelich

The classification outcome should reflect a high uncertainty on ambiguous in-distribution samples that lie close to the decision boundary.

Explaining the Black-box Smoothly- A Counterfactual Approach

no code implementations11 Jan 2021 Sumedha Singla, Motahhare Eslami, Brian Pollack, Stephen Wallace, Kayhan Batmanghelich

We adopted a Generative Adversarial Network (GAN) to generate a progressive set of perturbations to a query image, such that the classification decision changes from its original class to its negation.

Subject2Vec: Generative-Discriminative Approach from a Set of Image Patches to a Vector

1 code implementation28 Jun 2018 Sumedha Singla, Mingming Gong, Siamak Ravanbakhsh, Frank Sciurba, Barnabas Poczos, Kayhan N. Batmanghelich

Our model consists of three mutually dependent modules which regulate each other: (1) a discriminative network that learns a fixed-length representation from local features and maps them to disease severity; (2) an attention mechanism that provides interpretability by focusing on the areas of the anatomy that contribute the most to the prediction task; and (3) a generative network that encourages the diversity of the local latent features.
