Multiclass Receiver Operating Characteristic (ROC) - scikit-learn
https://scikit-learn.org/stable/auto_examples/model_selection/plot_roc.html
WebMulticlass Receiver Operating Characteristic (ROC) ¶. This example describes the use of the Receiver Operating Characteristic (ROC) metric to evaluate the quality of multiclass classifiers. ROC curves typically feature true positive rate (TPR) on the Y axis, and false positive rate (FPR) on the X axis. This means that the top left corner of ...

WebOct 10, 2023 · We can plot a ROC curve for a model in Python using the roc_curve() scikit-learn function. The function takes both the true outcomes (0,1) from the test set and the predicted probabilities for the 1 class. The function returns the false positive rates for each threshold, true positive rates for each threshold and thresholds.
