Multiclass classification evaluation with ROC Curves and ROC AUC

Adapting the most used classification evaluation metric to the multiclass classification problem with OvR and OvO strategies

When evaluating multiclass classification models, we sometimes need to adapt the metrics used in binary classification to work in this setting. We can do that by using OvR and OvO strategies.

In this article I will show how to adapt ROC Curve and ROC AUC metrics for multiclass classification.

The ROC Curve and the ROC AUC score are important tools …
