Replying to @AntonioPuri00
@AntonioPuri00 and @frances55037016 recently delivered two seminars at Charles University in Prague: one on the evolution of recommender systems up to Sheaf Neural Networks, and one on how physics principles like entropy & renormalization groups can guide learning across domains.
