Synthetic Data Generation and Multi-Task Learning for Extracting Temporal Information from Health-Related Narrative Text

no code implementations WNUT (ACL) 2021 Heereen Shim, Dietwig Lowet, Stijn Luca, Bart Vanrumste

Also, we propose a novel multi-task temporal information extraction model and investigate whether multi-task learning can contribute to performance improvement by exploiting additional training signals with the existing training data.

On the Calibration of Probabilistic Classifier Sets

no code implementations20 May 2022 Thomas Mortier, Viktor Bengs, Eyke Hüllermeier, Stijn Luca, Willem Waegeman

In this paper, we extend the notion of calibration, which is commonly used to evaluate the validity of the aleatoric uncertainty representation of a single probabilistic classifier, to assess the validity of an epistemic uncertainty representation obtained by sets of probabilistic classifiers.
