WebThe ‘l2’ penalty is the standard used in SVC. The ‘l1’ leads to coef_ vectors that are sparse. Specifies the loss function. ‘hinge’ is the standard SVM loss (used e.g. by the SVC class) while ‘squared_hinge’ is the square of the hinge loss. The combination of penalty='l1' and loss='hinge' is not supported. WebThe improved SVM algorithm is based on the grid search method to optimize the parameters C and g in the SVM.
