What's the best SVM implementation of SVMs in MATLAB? Right now I'm looking at PEGASOS and SVM-Perf, which both claims to have good performance with large datasets and classes. But there are so many implementation out there, and I definitely missed some. Can I get some other recommendations?

My application is in bags of word object recognition that uses the histogram of the words in classification.

libsvm is a good choice. – shabbychef Jun 22 '12 at 23:26

Liblinear Library is the best choice ever (especially for large-scale problems). It has interfaces for MatLab/Octave, Python, Java, etc.

and you can introduce some non-linearity by computing for example homogeneous kernel maps. – sietschie Aug 2 '12 at 12:20
