Web9 aug. 2024 · How to Interpret a ROC Curve. The more that the ROC curve hugs the top left corner of the plot, the better the model does at classifying the data into categories. To quantify this, we can calculate the AUC (area under the curve) which tells us how much of the plot is located under the curve. The closer AUC is to 1, the better the model. how are indians treated in japan
