WeiPer: OOD Detection using Weight Perturbations of Class Projections

NeurIPS 2024poster

Recent advances in out-of-distribution (OOD) detection on image data show that pre-trained neural network classifiers can separate in-distribution (ID) from OOD data well, leveraging the class-discriminative ability of the model itself. Methods have been proposed that either use logit information di…

Chaotic Dynamics are Intrinsic to Neural Network Training with SGD

NeurIPS 2022accept

With the advent of deep learning over the last decade, a considerable amount of effort has gone into better understanding and enhancing Stochastic Gradient Descent so as to improve the performance and stability of artificial neural network training. Active research fields in this area include exploi…

Do Users Benefit From Interpretable Vision? A User Study, Baseline, And Dataset

ICLR 2022poster

A variety of methods exist to explain image classification models. However, whether they provide any benefit to users over simply comparing various inputs and the model’s respective predictions remains unclear. We conducted a user study (N=240) to test how such a baseline explanation technique perfo…

When Explanations Lie: Why Many Modified BP Attributions Fail

ICML 2020poster

Attribution methods aim to explain a neural network’s prediction by highlighting the most relevant image areas. A popular approach is to backpropagate (BP) a custom relevance score using modified rules, rather than the gradient. We analyze an extensive set of modified BP methods: Deep Taylor Decompo…
