https://work.caltech.edu/telecourse.html https://work.caltech.edu/telecourse.html This is a real Caltech course, not a made-for-online offering.

The course covers the theory and mathematics behind various machine learning techniques. It's not a practical course that just teaches you to use some particular library.
