How to train fitcecoc by using COST SENSITIVE SVM

37 views (last 30 days)
Dear, I have a multiclass problem with an highly unbalanced dataset.
How can I train a multiclass, error-correcting output codes (ECOC) model using svm cost sensitive svm?
If I use svm for a binary classifier I would just set the cost matrix.
However, here we have a multiclass poroblem and ECOC models perform much better.

MATLAB provides ClassificationECOC and fitcecoc for Multiclass model for support vector machines (SVMs) and other classifiers.
The documentation here might help you.
