  During the period, I collaborated with the group coordinated by Prof. Anthony C. Coolen. The research subject has been focused on the development of an interpretable spin-glass theory for learning procedure of Restricted Boltzmann Machines. In particular, fundamental operating regimes (in terms of the hyperparameters of the training procedure) and glassy behavior has been analyzed, both theoretical and numerically.

Meanwhile, I collaborated to the research group coordinated by Prof. Davide Fioravanti (Alma Mater Studiorum). The research subjects involved the relation between supersymmetric gauge theories with classical and quantum integrable systems, and correspondence between supersymmetric gauge theories on deformed backgrounds and conformal field theories.
  

• 16-23 January 2023

  During the period, I attended the workshop "Physics-informed Machine-Learning", in which I took part to stimulating discussions about statistical mechanics of spin glasses and their application to Artificial Intelligence. I also gave a talk at the workshop about Dreaming Neural Networks and the possibility to extended the theory to Boltzmann Machines.

  Ref: Prof. Alessia Annibale
  During the period, we discussed several topics in statistical mechanics of spin glasses, especially concerning the application of Machine Retrieval models to the theoretical modeling of biological processes. In this period, I also gave an invited talk. Finally, I also had the chance to discuss with brilliant researchers and professors, in particular with Prof. Reimer Kuhn.
