Machine Learning has become a tremendous field as a result of its success. If you want to focus on the computational side of ML then here are some great options:
University of Alberta: Rich Sutton, Csaba Szepsevari, Mike Bowling
Brown University: Michael Littman, Stefanie Tellex
University of Michigan: Satinder Singh
Mcgill University: Doina Precup and Joelle Pineau
University College of London: Peter Dayan
But if you want to pursue a Machine Learning Training from a reputable institute, I would suggest Intellipaat, as the insights provided by their faculties will make one to master the domain.
