This tutorial with real R code demonstrates how to create a predictive model using cforest (Breiman’s random forests) from the package party, evaluate the predictive model on a separate set of data, and then plot the performance using ROC curves and a lift chart. These charts are useful for...

scikit-learn是一个用于机器学习的Python库,提供了丰富的工具和算法来支持数据预处理、特征工程、模型选择和评估等任务。其中,plot_roc_curve是scikit-learn中的一个函数,用于绘制接收者操作特征曲线(Receiver Operating Characteristic Curve,简称ROC曲线)。
Maybe we should drop parameter pos_label in plot_roc_curve, because we do not have parameter pos_label in roc_auc_score. In roc_auc_score, for binary y_true, y_score is supposed to be the score of the class with greater label. Sorry, something went wrong. qinhanmin2014 added Blocke...
Similarly to the example provided here: https://scikit-learn.org/stable/auto_examples/model_selection/plot_precision_recall.html, extend plot_precision_recall_curve and plot_roc_curve to be able to deal with multiclass scenarios. 👍 1
Machine Learning - Area under the curve (AUC) The Area under the curve (AUC) is a performance metrics for a binary classifiers. By comparing the ROC curves with the area under the curve, or AUC, it captures the extent to which the curve is up in the... Statistics Learning - (Error...
