Java interface for Vowpal Wabbit.
Built upon the original JNI code from Vowpal Wabbit and build system from Indeed's vowpal-wabbit-java.
VWScalarsLearner vw = VWLearners.create("--oaa 3 --holdout_period 9 --passes 10 --cache_file vw.cache --loss_function=logistic --probabilities");
vw.learn("1 | c d e");
float[] pred = vw.predict("c d e");
vw.saveModel("model.vw");
vw.close();
