[Sep 22nd 2021] LabMeeting: Trustworthy and Explainable Artificial Intelligence: an application to complex genetic diseases

Nicola Picchiotti (University of Pavia) When: Sep 22nd, 2021 – 11:00 – 11:45 AM Where: Google meet link Description The “black box” nature of deep neural network models is often a limit for safe applications since the reliability of the model predictions can be affected by the incompleteness in the optimization problem formalization. To frame […]

[Sep 8th 2021] LabMeeting: Entropy-based Logic Explanations of Neural Networks

Gabriele Ciravegna (University of Siena) When: Sep 8th, 2021 – 11:00 – 11:45 AM Where: Google meet link Description Explainable artificial intelligence has rapidly emerged since lawmakers have started requiring interpretable models for safety-critical domains. Concept-based neural networks have arisen as explainable-by-design methods as they leverage human-understandable symbols (i.e. concepts) to predict class memberships. However, […]

[Jul 27th 2021] LabMeeting: Continuous Action Spaces vs Discrete Action Spaces in Reinforcement Learning: a Practical Example

Luca Pasqualini (University of Siena) When: Jul 27th, 2021 – 11:00 – 11:45 AM Where: Google meet link Description In reinforcement learning, with the exception of some control problems, de-facto continuous action spaces are rare. They have a powerful feature though: they can be used to reduce the complexity of combinatorial discrete action spaces. Through […]
