Generalized Conformal Predictive Systems Under Distributional Shifts
Jef Jonkers, Johanna Ziegel
Conformal predictive systems (CPS) output calibrated bands of CDFs under exchangeability. We extend generalized CPS to non-exchangeable settings by encoding distributional shifts t…
Proper Scoring Rules for Right-Censored Survival Data
Jef Jonkers, Glenn Van Wallendael, Luc Duchateau +1
Proper scoring rules provide a rigorous theoretical basis for the training and evaluation of probabilistic forecasts. However, in the presence of right censoring, the event time is…
Reliable uncertainty quantification for 2D/3D anatomical landmark localization using multi-output conformal prediction
Jef Jonkers, Frank Coopman, Luc Duchateau +2
Automatic anatomical landmark localization in medical imaging requires not just accurate predictions but reliable uncertainty quantification for effective clinical decision support…
landmarker: a Toolkit for Anatomical Landmark Localization in 2D/3D Images
Jef Jonkers, Luc Duchateau, Glenn Van Wallendael +1
Anatomical landmark localization in 2D/3D images is a critical task in medical imaging. Although many general-purpose tools exist for landmark localization in classical computer vi…
