Sklearn outputcodeclassifier
WebbThe ‘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. WebbOutputCodeClassifier. Output-code multiclass strategy. This also referred to as "error-correcting output codes". This class allows to learn a multi-class classification problem with a binary classifier. Each class is converted to a code of 0s and 1s. The length of the code is called the code size. A copy of the classifier made for code.
