Parameters estimator estimator instance. Fitted classifier or a fitted Pipeline in which the last estimator is a classifier.. X {array-like, sparse matrix} of shape (n_samples, n_features). Input values. y_true array-like of shape (n_samples,). Target values. labels array-like of shape (n_classes,), default=None. List of labels to index the matrix. This may be used to reorder or …

sklearn.metrics.confusion_matrix(y_true, y_pred, *, labels=None, sample_weight=None, normalize=None) [source] ¶. Compute confusion matrix to evaluate the accuracy of a classification. By definition a confusion matrix C is such that C i, j is equal to the number of observations known to be in group i and predicted to be in group j.

Notes. The multilabel_confusion_matrix calculates class-wise or sample-wise multilabel confusion matrices, and in multiclass tasks, labels are binarized under a one-vs-rest way; while confusion_matrix calculates one confusion matrix for confusion between every two classes.. Examples. Multilabel-indicator case: >>> import numpy as np >>> from sklearn.metrics import …
