Webe. In machine learning and statistical classification, multiclass classification or multinomial classification is the problem of classifying instances into one of three or more classes (classifying instances into one of two classes is called binary classification ). While many classification algorithms (notably multinomial logistic regression ... WebBinary classification . Multi-class classification. No. of classes. It is a classification of two groups, i.e. classifies objects in at most two classes. There can be any number of classes in it, i.e., classifies the object into more than two classes.
