Amazing ML visualization software

I stumbled upon this by viewing Nirod's Priell mailing archives. MLDemos is a beautiful
ML visualization software which can be very useful when trying to understand the different  ML methods.

I installed MLDemos easily using the MAC .dmg file. Here are some images I created
when playing with the software. There are two classes: red and white points.
Here is classification using kernelized SVM:

And the same problem solved using linear SVM:

And using sigmoids:

The disks are the support vectors.

The apparent drawback is that visualization is done using two dimensions. This software does not replace the need of studying ML methods, but gives a very nice visualization that
helps understand the different methods.
