WebMetrics Module (API Reference) The scikitplot.metrics module includes plots for machine learning evaluation metrics e.g. confusion matrix, silhouette scores, etc. y_true ( array-like, shape (n_samples)) – Ground truth (correct) target values. y_pred ( array-like, shape (n_samples)) – Estimated targets as returned by a classifier. WebThe lift chart is derived from the cumulative gains chart; the values on the y axis correspond to the ratio of the cumulative gain for each curve to the baseline. Thus, the lift at 10% for the category Yes is 30%/10% = 3.0. It provides another way of looking at the information in the cumulative gains chart. can imac screen record
