The list below is the set of possible reading courses which can be offered by the Phd Program. Each academic year, on the basis of the didactic requirements of the incoming PhD students, the Council will select the ones to be activated.
Reading courses activated in the first semester of the academic year 2017-2018:
(1) Mathematics for Artificial Intelligence
Introduction to neural networks: genesis and future perspectives.
Basics of statistical mechanics and statistical inference.
Neural networks for associative memory and pattern recognition.
Hopfield model.
Rosenblatt and Minsky&Papert perceptrons.
Neural networks for statistical learning and feature discovery.
Supervised Boltzmann machines.
Unsupervised Boltzmann machines.
Bayesian equivalence between Hopfield retrieval and Boltzmann learning.
Multilayered Boltzmann machines and deep learning.
Advanced topics: Numerical tools for machine learning; Non-mean-field neural networks; (Bio-)Logic gates; Maximum entropy approach, Hamilton-Jacobi techniques for mean-field models.
