WebMar 12, 2024 · 1 It should be ok. In sklearn the label encoder usually encodes it as 0,1,2,3 if your class labels are say a,b,c,d. Onehot encoding is normally used for transforming your independent variable. What you are looking for is multi-class classification. It is implemented in both svm and logistic regression. We use the iris dataset as an example: WebMar 25, 2024 · Mainly there are two methods for Multiclass classification in SVM. One-against-one method: This method constructs k (k − 1)/2 classifiers where each one is trained on data from two classes....

WebOct 17, 2024 · SVM is one of the supervised learning models used for regression analysis and classification problems. It uses the nearest training data points of each data to build one or more hyperplanes to classify high-dimensional data. It maximizes the margin between them as much as possible (De la Hoz et al. 2015 ).
