Meta-Learning the Search Distribution of Black-Box Random Search Based Adversarial Attacks

Maksym Yatsura, Jan Hendrik Metzen, Matthias Hein

Adversarial attacks based on randomized search schemes have obtained state-of-the-art results in black-box robustness evaluation recently. However, as we demonstrate in this work,…

Being a Bit Frequentist Improves Bayesian Neural Networks

Agustinus Kristiadi, Matthias Hein, Philipp Hennig

Despite their compelling theoretical properties, Bayesian neural networks (BNNs) tend to perform worse than frequentist methods in classification-based uncertainty quantification (…

Provably Robust Detection of Out-of-distribution Data (almost) for free

Alexander Meinke, Julian Bitterwolf, Matthias Hein

The application of machine learning in safety-critical systems requires a reliable assessment of uncertainty. However, deep neural networks are known to produce highly overconfiden…

Adversarial Robustness against Multiple and Single -Threat Models via Quick Fine-Tuning of Robust Classifiers

Francesco Croce, Matthias Hein

A major drawback of adversarially robust models, in particular for large scale datasets like ImageNet, is the extremely long training time compared to standard ones. Moreover, mode…

Relating Adversarially Robust Generalization to Flat Minima

David Stutz, Matthias Hein, Bernt Schiele

Adversarial training (AT) has become the de-facto standard to obtain models robust against adversarial examples. However, AT exhibits severe robust overfitting: cross-entropy loss…
