When Medical Imaging Met Self-Attention: A Love Story That Didn't Quite Work Out

no code implementations18 Apr 2024 Tristan Piater, Niklas Penzel, Gideon Stein, Joachim Denzler

To evaluate this trend for medical imaging, we extend two widely adopted convolutional architectures with different self-attention variants on two different medical datasets.

Reducing Bias in Pre-trained Models by Tuning while Penalizing Change

no code implementations18 Apr 2024 Niklas Penzel, Gideon Stein, Joachim Denzler

If later such a bias is discovered during inference or deployment, it is often necessary to acquire new data and retrain the model.

Embracing the black box: Heading towards foundation models for causal discovery from time series data

1 code implementation14 Feb 2024 Gideon Stein, Maha Shadaydeh, Joachim Denzler

Our empirical findings suggest that causal discovery in a supervised manner is possible, assuming that the training and test time series samples share most of their dynamics.
