If you are interested in learning the basics of Machine Learning I really recommend Andrew Ng's course on Coursera[0]. It starts off very basic and requires almost no prior knowledge other than some linear algebra. It evolves to more advance topics like Neural Networks, Support Vector Machines, Recommender Systems, etc. It is amazing how much you can do after just a few weeks of lessons. It's a very practical course with real world examples and exercises each week. The focus is mostly on using and implementing machine learning algorithms and less so on how and why the math behind them works. (To me this is a negative, but I'm sure some people will appreciate that.)
