Professor Andrew Ng from Stanford University will offer his class on Machine learning for free to anyone on the web. All you have to do is visit the site and sign-up. Non-Stanford students will have to follow the same pace as regular students, but will not get college credits for completing the course, but will get a certificate of completion.
