Diversified Adversarial Attacks based on Conjugate Gradient Method

ICML 2022spotlight

Deep learning models are vulnerable to adversarial examples, and adversarial attacks used to generate such examples have attracted considerable research interest. Although existing methods based on the steepest descent have achieved high attack success rates, ill-conditioned problems occasionally re…

Nested Subspace Arrangement for Representation of Relational Data

ICML 2020poster

Studies of acquiring appropriate continuous representations of a discrete objects such as graph and knowledge based data have been conducted by many researches in the field of machine learning. In this paper, we introduce Nested SubSpace arrangement (NSS arrangement), a comprehensive framework for r…
