A carrier type for the liblinear algorithm type. It really wants to be a set of enums with different type parameters, but it's encoded as an interface where each subclass for an Output implementation contains an enum with it's valid values.

LibLinear supported enum values for various tasks are:

• L2R_LR - L2-regularized logistic regression (primal)
• L2R_L2LOSS_SVC_DUAL - L2-regularized L2-loss support vector classification (dual)
• L2R_L2LOSS_SVC - L2-regularized L2-loss support vector classification (primal)
• L2R_L1LOSS_SVC_DUAL - L2-regularized L1-loss support vector classification (dual)
• MCSVM_CS - multi-class support vector classification by Crammer and Singer
• L1R_L2LOSS_SVC - L1-regularized L2-loss support vector classification
• L1R_LR - L1-regularized logistic regression
• L2R_LR_DUAL - L2-regularized logistic regression (dual)
• L2R_L2LOSS_SVR - L2-regularized L2-loss support vector regression (primal)
• L2R_L2LOSS_SVR_DUAL - L2-regularized L2-loss support vector regression (dual)
• L2R_L1LOSS_SVR_DUAL - L2-regularized L1-loss support vector regression (dual)
