To Ask or Not to Ask: Learning to Require Human Feedback

Andrea Pugnana, Giovanni De Toni, Cesare Barbera +3

Developing decision-support systems that complement human performance in classification tasks remains an open challenge. A popular approach, Learning to Defer (LtD), allows a Machi…

Multiclass Local Calibration with the Jensen-Shannon Distance

Cesare Barbera, Lorenzo Perini, Giovanni De Toni +2

Developing trustworthy Machine Learning (ML) models requires their predicted probabilities to be well-calibrated, meaning they should reflect true-class frequencies. Among calibrat…

Personalized Algorithmic Recourse with Preference Elicitation

Giovanni De Toni, Paolo Viappiani, Stefano Teso +2

Algorithmic Recourse (AR) is the problem of computing a sequence of actions that -- once performed by a user -- overturns an undesirable machine decision. It is paramount that the…

Synthesizing explainable counterfactual policies for algorithmic recourse with program synthesis

Giovanni De Toni, Bruno Lepri, Andrea Passerini

Being able to provide counterfactual interventions - sequences of actions we would have had to take for a desirable outcome to happen - is essential to explain how to change an unf…

Learning compositional programs with arguments and sampling

Giovanni De Toni, Luca Erculiani, Andrea Passerini

One of the most challenging goals in designing intelligent systems is empowering them with the ability to synthesize programs from data. Namely, given specific requirements in the…
