A bold experiment in distributed education, "Machine Learning" will be offered free and online to students worldwide during the fall of 2011. Students will have access to lecture videos, lecture notes, receive regular feedback on progress, and receive answers to questions. When you successfully complete the class, you will also receive a statement of accomplishment. Taught by Professor Andrew Ng, the curriculum draws from Stanford's popular Machine Learning course.
I went through the Introduction videos, it's quite nice and interesting.
