Stanford University CS221: Introduction to one-quarter of Intelligence artificial fall 2011 is now available, free of charge, Stanford announced.
You can take this online course of Prof. Sebastian Thrun and Peter Norvig, with several hundred college students Stanford, without having to fill out an application, pay tuition, or live in a dormitory.
It is more than just downloading of materials and following with a live stream; in fact, you will have to work just as well as Stanford students. There is a book, at least 10 hours per week of studies, weekly graded homework, a mid-term review and a final examination. Teachers will be available to answer your questions. If you have finished the work, you will get a certificate of completion and a final note (no College not credits, however, unless you are a Stanford student).
