How to create a ROC curve in R - DataTechNotes
WebJun 23, 2015 · This non-uniformity of the cost function causes ambiguities if ROC curves of different classifiers cross and on itself when the ROC curve is compressed into the AUC by means of integration over the false positive rate. However, the AUC also has a much more serious deficiency, and one which appears not to have been previously recognised. WebMost commonly used metrics for multi-classes are F1 score, Average Accuracy, Log-loss. This function has been much less tested than the rest of the package and It seems you are looking for multi-class ROC analysis, which is a kind of multi-objective optimization covered in a tutorial at ICML'04.

WebR Documentation Plot a ROC curve Description This function plots a ROC curve. It can accept many arguments to tweak the appearance of the plot. Two syntaxes are possible: … WebDescription This function creates Receiver Operating Characteristic (ROC) plots for one or more models. A ROC curve plots the false alarm rate against the hit rate for a probablistic forecast for a range of thresholds. The area under the curve is viewed as a measure of a forecast's accuracy. A measure of 1 would indicate a perfect model.
