Learning Behavioral Soft Constraints from Demonstrations

no code implementations21 Feb 2022 Arie Glazier, Andrea Loreggia, Nicholas Mattei, Taher Rahgooy, Francesca Rossi, Brent Venable

Many real-life scenarios require humans to make difficult trade-offs: do we always follow all the traffic rules or do we violate the speed limit in an emergency?

Deep ensembles in bioimage segmentation

no code implementations24 Dec 2021 Loris Nanni, Daniela Cuza, Alessandra Lumini, Andrea Loreggia, Sheryl Brahnam

Semantic segmentation consists in classifying each pixel of an image by assigning it to a specific label chosen from a set of all the available ones.

Making Human-Like Trade-offs in Constrained Environments by Learning from Demonstrations

no code implementations22 Sep 2021 Arie Glazier, Andrea Loreggia, Nicholas Mattei, Taher Rahgooy, Francesca Rossi, K. Brent Venable

To this end, we propose a novel inverse reinforcement learning (IRL) method for learning implicit hard and soft constraints from demonstrations, enabling agents to quickly adapt to new settings.

Modeling Contrary-to-Duty with CP-nets

no code implementations23 Mar 2020 Roberta Calegari, Andrea Loreggia, Emiliano Lorini, Francesca Rossi, Giovanni Sartor

In a ceteris-paribus semantics for deontic logic, a state of affairs where a larger set of prescriptions is respected is preferable to a state of affairs where some of them are violated.

Voting with Random Classifiers (VORACE): Theoretical and Experimental Analysis

no code implementations18 Sep 2019 Cristina Cornelio, Michele Donini, Andrea Loreggia, Maria Silvia Pini, Francesca Rossi

In many machine learning scenarios, looking for the best classifier that fits a particular dataset can be very costly in terms of time and resources.

CPMetric: Deep Siamese Networks for Learning Distances Between Structured Preferences

no code implementations21 Sep 2018 Andrea Loreggia, Nicholas Mattei, Francesca Rossi, K. Brent Venable

CPDist is a novel metric learning approach based on the use of deep siamese networks which learn the Kendal Tau distance between partial orders that are induced by compact preference representations.
