This is a wrapper for the svmlight library. It allows you to specify an unbiased hyperplane. It also allows you to access the learnt hyperplane after training.
See the svmlight website (http://svmlight.joachims.org/) for full details.
Example of use:
>>> f = DocumentFactory()
>>> docs = [f.new(x.split()) for x in [
... "this is a nice long document",
... "this is another nice long document",
... "this is rather a short document",
... "a horrible document",
... "another horrible document"]]
>>> l = Learner()
>>> model = l.learn(docs, [1, 1, 1, -1, -1])
>>> judgments = [model.classify(d) for d in docs]
>>> print model.plane, model.biasBuilding requires Cython to be installed. Type
$ python setup.py build
$ python setup.py install
in the root directory to build and install.
