This is nice, so is libsvm, and a few other comercial products I've used (JMP), but having some fairly non-trivial data sets for work, I've found myself implementing most of these by hand to get out the results I want. I'm not in an internet data mining field, most of my data comes from Semiconductors, so do these actually work well (as in 85%+ accuracy) on those type data sets?
This is highly problem dependent. libsvm will give some of the best results off-the-shelf, assume that your input features are sane. If not, you might need to do something more sophisticated. You can email me (see profile) if you want more information.
