It's interesting that MITx is being explicit that their courses will be hard. This provides an interesting market differentiation in the online learning space. The recent Stanford classes & Udacity seem to be aiming for a much more general audience.
That's not true. The Stanford AI class up front said that it required a lot of math. I ended up dropping out because I couldn't catch up quickly enough with the math requirement to complete the course as well.
So for those of us who would like to take this course eventually but don't necessarily have the appropriate math experience in, oh, the last decade or so, are there resources online (or even by book) which would give adequate preparation in a reasonable timeframe?
The class was fairly hard if the material was new to you. However, the only math was probability. If you review basic probability you should be just fine.
