Adults as Augmentations for Children in Facial Emotion Recognition with Contrastive Learning

no code implementations10 Feb 2022 Marco Virgolin, Andrea De Lorenzo, Tanja Alderliesten, Peter A. N. Bosman

Our results indicate that adult data can be considered to be a meaningful augmentation of pediatric data for the recognition of emotional facial expression in children, and open up the possibility for other applications of contrastive learning to improve pediatric care by complementing data of children with that of adults.

Model Learning with Personalized Interpretability Estimation (ML-PIE)

1 code implementation13 Apr 2021 Marco Virgolin, Andrea De Lorenzo, Francesca Randone, Eric Medvet, Mattias Wahde

The latter is estimated by a neural network that is trained concurrently to the evolution using the feedback of the user, which is collected using uncertainty-based active learning.

Learning a Formula of Interpretability to Learn Interpretable Formulas

3 code implementations23 Apr 2020 Marco Virgolin, Andrea De Lorenzo, Eric Medvet, Francesca Randone

We show that it is instead possible to take a meta-learning approach: an ML model of non-trivial Proxies of Human Interpretability (PHIs) can be learned from human feedback, then this model can be incorporated within an ML training process to directly optimize for interpretability.
