Addressing Discrepancies in Semantic and Visual Alignment in Neural Networks

no code implementations1 Jun 2023 Natalie Abreu, Nathan Vaska, Victoria Helus

We evaluate whether the method increases semantic alignment by evaluating model performance on adversarially perturbed data, with the idea that it should be easier for an adversary to switch one class to a similarly represented class.

Addressing Mistake Severity in Neural Networks with Semantic Knowledge

no code implementations21 Nov 2022 Natalie Abreu, Nathan Vaska, Victoria Helus

Most robust training techniques aim to improve model accuracy on perturbed inputs; as an alternate form of robustness, we aim to reduce the severity of mistakes made by neural networks in challenging conditions.
