Actually, I am porting a code for Gaussian Mixture Models with batch and
online EM. I first try to do a pure python version to get an idea on
scipy capabilities, and then I intend to create the stub to a C
implementation (which already exists for matlab, the core being
independant of matlab). I am hoping to have a much cleaner
implementation, and more extensible (ie using other pdf, and why not
more general models) using python
languages capabilities (module, inheritance, etc...).
I think porting netlab would be a huge task, and quite difficult; there
is also torch (http://www.torch.ch/) which may be interesting to use
(C++ code, BSD license). Having a machine learning tool box would be a
step forward for scipy, I guess.
