The first lecture of Caltech's CS 156 Machine Learning course by Yaser Abu-Mostafa, introducing the learning problem and supervised, unsupervised and reinforcement learning. It is one of 18 lectures in the Learning from Data course.

Why HN likes it: Recommended repeatedly in 'where do I start with ML' threads as a clear, math-aware introduction.

“I have found the Caltech machine learning intro course to be the most elucidating of any resource so far”
