Just watched the first video, it's a very nice intro to the mathematics behind neural networks, personally I like Jeremy & Rachel Howards video course [1] a lot better because it is much more geared towards practical applications but if you're into the theory end of things or if you simply want to understand better what is going on behind the scenes this video is really quite good and well worth your time.<p>[1] <a href="http://course.fast.ai/" rel="nofollow">http://course.fast.ai/</a>
