I'm pretty sure that it does have regularization. The optimization process penalizes model complexity in addition to maximizing the fit to the data.

Eureqa does model selection as part of the optimization, so that would be an advantage over vanilla linear regression. Of course, there are a lot of specialized model selection techniques for linear regression that would probably be better.

I attended a talk by one of the designers. Some of Watson's 'wrong' answers he described were pretty funny. There was one where the clue (paraphrasing) was 'Punch below the beltline that rhymes' and the right answer was 'Low blow', but Wats

According to the designers Watson waits for the light indicators (not seen on TV) that you can press the button, so no lockout. Humans often try to predict when the light will turn on instead of waiting, so sometimes they press the button f

I would call R 'Matlab for statisticians'. They're similar in that they are matrix-oriented scripting languages. The main difference is their focus, which matters mainly in regards to what kind of libraries you'll find for either.

A pair of cheap usb webcams are pretty suboptimal for stereo vision. To start, they aren't synchronized. Plus you have to rig them somehow to know their relative positions. They may use rolling shutter, which is bad for stereo. It's not tha

As in, the look and feel of the page isn't very Web 2.0? I agree, but I don't think it has that much to do with the education itself, at least not the programmer's education. I was thinking something related to the fact that the best univer

My casual estimate as a Chilean: A lot of the more tech-savvy/well-off people have iphones. There's a handful of Blackberries out there and virtually no Androids. Most people have dumb-phones.
