Details of liblinar options
    -s type : set type of solver (default 1)
      for multi-class classification
             0 -- L2-regularized logistic regression (primal)
             1 -- L2-regularized L2-loss support vector classification (dual)
             2 -- L2-regularized L2-loss support vector classification (primal)
             3 -- L2-regularized L1-loss support vector classification (dual)
             4 -- support vector classification by Crammer and Singer
             5 -- L1-regularized L2-loss support vector classification
             6 -- L1-regularized logistic regression
             7 -- L2-regularized logistic regression (dual)
      for regression
            11 -- L2-regularized L2-loss support vector regression (primal)
            12 -- L2-regularized L2-loss support vector regression (dual)
            13 -- L2-regularized L1-loss support vector regression (dual)
    -c cost : set the parameter C (default 1)
    -p epsilon : set the epsilon in loss function of epsilon-SVR (default 0.1)
    -e epsilon : set tolerance of termination criterion
            -s 0 and 2
                    |f'(w)|_2 <= eps*min(pos,neg)/l*|f'(w0)|_2,
                    where f is the primal function and pos/neg are # of
                    positive/negative data (default 0.01)
            -s 11
                    |f'(w)|_2 <= eps*|f'(w0)|_2 (default 0.001) 
            -s 1, 3, 4 and 7
                    Dual maximal violation <= eps; similar to libsvm (default 0.1)
            -s 5 and 6
                    |f'(w)|_inf <= eps*min(pos,neg)/l*|f'(w0)|_inf,
                    where f is the primal function (default 0.01)
            -s 12 and 13\n"
                    |f'(alpha)|_1 <= eps |f'(alpha0)|,
                    where f is the dual function (default 0.1)
    -B bias : if bias >= 0, instance x becomes [x; bias]; if < 0, no bias term added (default -1)
    -wi weight: weights adjust the parameter C of different classes (see README for details)
    -v n: n-fold cross validation mode
    -q : quiet mode (no outputs)
