Efficient Credal Prediction through Decalibration

Paul Hofman, Timo Löhr, Maximilian Muschalik +2

A reliable representation of uncertainty is essential for the application of modern machine learning methods in safety-critical settings. In this regard, the use of credal sets (i.…

Credal Prediction based on Relative Likelihood

Timo Löhr, Paul Hofman, Felix Mohr +1

Predictions in the form of sets of probability distributions, so-called credal sets, provide a suitable means to represent a learner's epistemic uncertainty. In this paper, we prop…

Label-wise Aleatoric and Epistemic Uncertainty Quantification

Yusuf Sale, Paul Hofman, Timo Löhr +3

We present a novel approach to uncertainty quantification in classification tasks based on label-wise decomposition of uncertainty measures. This label-wise perspective allows unce…
