Missing machine learning and AI tools

[GoogleCodeExporter]

I'd like to congratulate the people involved in putting pythonxy together. 
Python xy has helped me a really big deal in my PhD thesis.

I think that adding the Python interface to libsvm or ELEFANT would just 
make Python xy just perfect for people doing research in computer vision, 
considering that it already has opencv in the package.

All the best,
Albino

I've been reading the svm.py module from libSVM and I found out that because of 
some 
issue they had with their Python binding they do not exclude zeros from their 
sparse 
data representation, therefore, the sparse representation is only there to make 
the 
whole thing totally inneficient.

In their website, specifically http://www.csie.ntu.edu.tw/~cjlin/libsvmtools/ , 
there is link for a dense data representation version of libsvm which 
approximately 
40% faster, however, without a Python binding.

If you guys are considering to include libSVM in the Python(x,y) distribution, 
a 
binding for the dense data libSVM version would be ideal.

Cheers,
Albino

obs.: Thank you guys for this wonderful project!

I would also like to support this request for a machine learning library, 
preferably
libsvm which is the most popular out there.
Concerning the the version for dense data, although it would be great to have it
added, the sparse version can still serve in many cases without significant 
problems.
Considering also the fact that it is currently available in python, I believe 
that it
can be directly and easily added to the core distribution, leaving the dense 
version
for a later stage.
Thanks

The new OpenCV version (2.0) Python binding fully supports the Machine Learning 
library 
that ships with OpenCV (includes AdaBoost,Support Vector Machines, Random 
Trees, Neural 
Networks, KMeans clustering, among others). Please, consider adding the OpenCV 
2.0 
python binding in the next update of Python(x,y).
