How to draw ROC curve for imbalanced multiclass classifier using MATLAB?

30 May 2020 0 9K Report

How to draw ROC curve for imbalanced multiclass (assume 4 classes) classifier.Found some articles regarding Micro and Macro averaging for multiclass data, but couldn't get any correct idea regarding ROC curve.For eg. In multiclass (4 classes) all positive and negative classes for each classes should consider together or separately.(working on matlab platform)

If any article regarding this please upload
