Overview

The aim of the course is to provide in-depth knowledge of the main machine learning and deep learning techniques for the analysis of heterogeneous data. In particular, the main data classification algorithms, temporal sequences of information and complex patterns such as images will be presented and analyzed. The main techniques of supervised and unsupervised machine learning will be presented.
Neural networks and how they work will also be illustrated. Present complex neural architectures for the analysis of spatial and temporal data and generative models. The rudiments of learning with reinforcement will also be provided.
