Learning from data: A machine learning course
I stumbled upon this course while looking for additional material for my data science course at Telecom Paris. The fact that a full complete course of this quality is freely available for everyone is almost unbelievable. The course is taught by Yaser Abu-Mostafa, a professor at Caltech, and is based on his book Learning from Data.
I think this is one of the best courses that I took that is freely available on the internet. The course material is available here. Below you can download the course notes I took.
