Class Equilibrium using Coulomb's Law

no code implementations25 Apr 2021 Saheb Chhabra, Puspita Majumdar, Mayank Vatsa, Richa Singh

Projection algorithms learn a transformation function to project the data from input space to the feature space, with the objective of increasing the inter-class distance.

Attack Agnostic Adversarial Defense via Visual Imperceptible Bound

no code implementations25 Oct 2020 Saheb Chhabra, Akshay Agarwal, Richa Singh, Mayank Vatsa

However, the lack of generalizability of existing defense algorithms and the high variability in the performance of the attack algorithms for different databases raises several questions on the effectiveness of the defense algorithms.
