A Comparative Study on Generative Models for High Resolution Solar Observation Imaging

1 code implementation14 Apr 2023 Mehdi Cherti, Alexander Czernik, Stefan Kesselheim, Frederic Effenberger, Jenia Jitsev

Starting from StyleGAN-based methods, we uncover severe deficits of this model family in handling fine-scale details of solar images when training on high resolution samples, contrary to training on natural face images.

Reproducible scaling laws for contrastive language-image learning

3 code implementations CVPR 2023 Mehdi Cherti, Romain Beaumont, Ross Wightman, Mitchell Wortsman, Gabriel Ilharco, Cade Gordon, Christoph Schuhmann, Ludwig Schmidt, Jenia Jitsev

To address these limitations, we investigate scaling laws for contrastive language-image pre-training (CLIP) with the public LAION dataset and the open-source OpenCLIP repository.

Effect of Pre-Training Scale on Intra- and Inter-Domain Full and Few-Shot Transfer Learning for Natural and Medical X-Ray Chest Images

1 code implementation31 May 2021 Mehdi Cherti, Jenia Jitsev

We then conduct supervised pre-training, while varying network size and source data scale and domain, being either large natural (ImageNet-1k/21k) or large medical chest X-Ray datasets, and transfer pre-trained models to different natural or medical targets.

Generalization over different cellular automata rules learned by a deep feed-forward neural network

1 code implementation27 Mar 2021 Marcel Aach, Jens Henrik Goebbert, Jenia Jitsev

To test generalization ability of a class of deep neural networks, we randomly generate a large number of different rule sets for 2-D cellular automata (CA), based on John Conway's Game of Life.

Adversarial domain adaptation to reduce sample bias of a high energy physics classifier

no code implementations1 May 2020 Jose M. Clavijo, Paul Glaysher, Judith M. Katzy, Jenia Jitsev

We apply adversarial domain adaptation in unsupervised setting to reduce sample bias in a supervised high energy physics events classifier training.

Obstacle Tower Without Human Demonstrations: How Far a Deep Feed-Forward Network Goes with Reinforcement Learning

1 code implementation1 Apr 2020 Marco Pleines, Jenia Jitsev, Mike Preuss, Frank Zimmer

The Obstacle Tower Challenge is the task to master a procedurally generated chain of levels that subsequently get harder to complete.

Using Physics-Informed Super-Resolution Generative Adversarial Networks for Subgrid Modeling in Turbulent Reactive Flows

no code implementations26 Nov 2019 Mathis Bode, Michael Gauding, Zeyu Lian, Dominik Denker, Marco Davidovic, Konstantin Kleinheinz, Jenia Jitsev, Heinz Pitsch

Reasons for this are the large amount of degrees of freedom in realistic flows, the high requirements with respect to accuracy and error robustness, as well as open questions, such as the generalization capability of trained neural networks in such high-dimensional, physics-constrained scenarios.
