Conformal Performance Range Prediction for Segmentation Output Quality Control

1 code implementation18 Jul 2024 Anna M. Wundram, Paul Fischer, Michael Muehlebach, Lisa M. Koch, Christian F. Baumgartner

Our results show that it is possible to achieve the desired coverage with small prediction ranges, highlighting the potential of performance range prediction as a valuable tool for output quality control.

Subgroup-Specific Risk-Controlled Dose Estimation in Radiotherapy

1 code implementation11 Jul 2024 Paul Fischer, Hannah Willms, Moritz Schneider, Daniela Thorwarth, Michael Muehlebach, Christian F. Baumgartner

We evaluate our algorithm on real clinical planing volumes from five different anatomical regions and show that our novel subgroup RCPS (SG-RCPS) algorithm leads to prediction intervals that jointly control the risk for multiple subgroups.

Uncertainty Estimation and Propagation in Accelerated MRI Reconstruction

1 code implementation4 Aug 2023 Paul Fischer, Thomas Küstner, Christian F. Baumgartner

We demonstrate that our proposed method produces high-quality reconstructions as well as uncertainty quantification that is substantially better calibrated than several strong baselines.

First Steps Towards a Runtime Analysis of Neuroevolution

no code implementations3 Jul 2023 Paul Fischer, Emil Lundt Larsen, Carsten Witt

We consider a simple setting in neuroevolution where an evolutionary algorithm optimizes the weights and activation functions of a simple artificial neural network.
