Machine Learning in a Year
I've been doing the Coursera ML course the past few weeks(started on the 22th of August). I can only give it my highest recommendation, it really is a great course. I did computer science in university(2.5 years) and have a decent grasp of calculus and linear algebra. I've also been programming for 9 or so years. I've found the course to be surprisingly simple and intuitive, but this probably varies with how comfortable you are with the math in the course.
