package linwrap

linwrap

Wrapper on top of liblinear-tools.

Linwrap can be used to train a L2-regularized logistic regression classifier or a linear Support Vector Regressor. You can optimize C (the L2 regularization parameter), w (the class weight) or k (the number of bags, i.e. use bagging). You can also find the optimal classification threshold using MCC maximization, use k-folds cross validation, parallelization, etc. In the regression case, you can only optimize C and epsilon.
