Three of our PhD students (Giuseppe Marra, Dario Zanca, and Andrea Zugarini, together with Giovanni Ciccone) won the Hackathon Mediaset Infinity, held in Rimini at Web Marketing Festival 2018. The goal of the challenge was to predict churn rate of users registered in infinitytv platform. Ten teams, composed of both students and professionals from Statistics […]

Some of these hyper-parameters are more related to the training procedure (epochs, learning rate, […]

Kremer, Professor (School of Computer and Science, University of Guelph, ON, CANADA) May 28, 2018 – 11:00 AM DIISM, Artificial Intelligence laboratory (room 201), Siena SI Description Biological systems, on all scales, are essentially information processing and control systems. From this perspective, analogies between biological processes and computational processes can be drawn. […]

Such human based labelling require a considerable effort that complicate the creation of large–scale datasets. In this […]
