OA-CutMix: Correcting the Label Bias of CutMix

Tobias Christian Nauen, Stanislav Frolov, Federico Raue, Brian Bernhard Moser, Andreas Dengel

CutMix assigns labels by patch area, not by visible object content, a systematic bias that mislabels 21.5% of samples and creates ghost labels in 17%. OA-CutMix replaces the label with one derived from object area, leaving the image mixing unchanged. It matches or beats 10+ static and dynamic mixing methods across 4 architectures and 6 datasets.

TextTeacher: What Can Language Teach About Images?

Tobias Christian Nauen, Stanislav Frolov, Brian Bernhard Moser, Federico Raue, Ahmed Anwar, Andreas Dengel

We use a frozen text encoder on image captions as a lightweight training-time auxiliary objective for image classifiers. The text components are dropped at inference, leaving a fast, unimodal vision model. Accuracy on ImageNet improves by up to +2.7 p.p. and downstream transfer by +1.0 p.p. on average, outperforming vision knowledge distillation at a fraction of the compute.

When Pretty Isn't Useful: Investigating Why Modern Text-to-Image Models Fail as Reliable Training Data Generators

Krzysztof Adamkiewicz, Brian Bernhard Moser, Stanislav Frolov, Tobias Christian Nauen, Federico Raue, Andreas Dengel

We show that newer text-to-image models are progressively worse as training data generators, despite better visual quality, because they collapse to a narrow aesthetic-centric distribution that diverges from real data.
