Scikit learn lift curve

Web24 Aug 2024 · Scikit-plot provides a method named plot_learning_curve () as a part of the estimators module which accepts estimator, X, Y, cross-validation info, and scoring metric for plotting performance of cross-validation on the dataset. Below we are plotting the performance of logistic regression on digits dataset with cross-validation. http://rasbt.github.io/mlxtend/user_guide/plotting/plot_learning_curves/
