I have collected a list of freely available courses on Machine Learning, Deep Learning, Reinforcement Learning, Natural Language Processing, Computer Vision, Probabilistic Graphical Models, Machine Learning Fundamentals, and Deep Learning boot camps or summer schools.
So I checked it and immediately got involved watching Ian Goodfellow …
Ian and his advisor wrote this book …. take a look at it.
Goodfellow posted pdfs of his talks here
