Welcome!

This is the official web site of Siena Artificial Intelligence Laboratory. The focus of our research is on machine learning. In the last few years, we’ve been mainly involved in the conception of new theories of learning in structured domains and in their applications to pattern recognition and mining the web. We are also interested […]

[May 12th 2021] LabMeeting: Graph Dynamic Embedding

Veronica Lachi (University of Siena) When: May 12, 2021 – 11:00 – 11:45 AM Where: Google meet link Description Representation learning of static and more recently dynamically evolving graphs has gained noticeable attention. Existing approaches for modelling graph dynamics focus extensively on the evolution of individual nodes independently of the evolution of mesoscale community structures. […]

[Apr 21st 2021] LabMeeting: A Representer Theorem for Deep Neural Networks

Giuseppe Alessio D’Inverno (University of Siena) When: Apr 21, 2021 – 11:00 – 11:45 AM Where: Google meet link Description We propose to optimize the activation functions of a deep neural network by adding a corresponding functional regularization to the cost function. We justify the use of a second- order total-variation criterion. This allows us […]

Local Propagation in Neural Network Learning by Architectural Constraints

Author: Matteo Tiezzi Date: March, 2021 Topics: Learning by Constraints; Constraint optimization; Graph Neural Networks; Lifelong Learning. Abstract A crucial role for the success of the Artificial Neural Networks (ANN) processing scheme has been played by the feed-forward propagation of signals. The input patterns undergo a series of stacked parametrized transformations, which foster deep feature […]

[Apr 14th 2021] LabMeeting: Incorporating network based protein complex discovery into automated model construction

Federica Baccini (University of Siena) When: Apr 14, 2021 – 11:00 – 11:45 AM Where: Google meet link Description We propose a method for gene expression based analysis of cancer phenotypes incorporating network biology knowledge through unsupervised construction of computational graphs. The structural construction of the computational graphs is driven by the use of topological […]

[Mar 31th 2021] LabMeeting: Logic Explainer Networks

Gabriele Ciravegna (University of Siena) When: Mar 31, 2021 – 11:00 – 11:45 AM Where: Google meet link Description Despite the increasing popularity of deep learning application, in real wold domains the employment of deep neural networks is still limited and strongly criticized due to their lack of interpretability. In particular, providing a comprehensible explanation […]

[Mar 24th 2021] LabMeeting: A precision medicine approach for patients treated with cannabinoids

Anna Visibelli (University of Siena) When: Mar 24, 2021 – 11:00 – 11:45 AM Where: Google meet link Description The plant Cannabis has been used for millennia for its medical and mind-altering effects. Clinical and preclinical research efforts over the past decades, have defined many effects of cannabis on physiology and behaviour and more recent […]
