Fast evaluation of the current driven by electron cyclotron waves for reactor studies

Published in Physics of Plasmas, 2018

In this paper, a procedure for the evaluation of the optimum current driven by EC waves for given global parameters is proposed, which relies on a single numerical calculation of the current drive efficiency, based on the adjoint method (including momentum-conserving corrections).

Leveraging Stochastic Predictions of Bayesian Neural Networks for Fluid Simulations

Published in NeurIPS, 2022

We investigate uncertainty estimation and multimodality via the non-deterministic predictions of Bayesian neural networks (BNNs) in fluid simulations. To this end, we deploy BNNs in three challenging experimental test-cases of increasing complexity.

In or Out? Fixing ImageNet Out-of-distribution detection

Published in ICML, 2023

We show that previously used datasets for evaluating OOD detection on ImageNet are severly flawed, because they contain a significant fraction of ID samples. We present NINCO, a novel hand-cleaned dataset as a solution.

Normalization Layers Are All That Sharpness-Aware Minimization Needs

Published in NeurIPS, 2023

We show that perturbing only the affine normalization parameters (roughly 0.1% of all parameters) in the adversarial step of SAM typically outperforms perturbing all of the parameters. This finding generalizes to different SAM variants and both BatchNorm and LayerNorm. Alternative sparse perturbation approaches do not achieve similar performance, especially not at such extreme sparsity levels.

How to rain your ViT for OOD Detection

Published in ICLR 2024 workshop on Responsible and Reliable Foundation Models, 2024

We investigate the impact of both the pretraining and finetuning scheme on the performance of ViTs on ImageNet-scale OOD detection by analyzing a large pool of models. We find that the exact type of pretraining has a strong impact on which method works well and on OOD detection performance in general.

LoGex: Improved tail detection of extremely rare histopathology classes via guided diffusion

Published in MICCAI 2024 ADSMI Workshop, 2024

In this paper, we aim to detect extremely rare tail-classes as out-of-distribution data. We leverage low-rank adaption (LoRA) and diffusion guidance to generate targeted synthetic data for the detection problem and significantly improve the tail detection performance on a challenging histopathological task without losing classification accuracy on the head classes.
