Confusion matrix — scikit-learn 1.1.2 documentation Example of confusion matrix usage to evaluate the quality of the output of a classifier on the iris data set. The diagonal elements represent the number of points for which the predicted label is equal to the true label, while off-diagonal elements are those that are mislabeled by the classifier.

Includes values in confusion matrix. xticks_rotation {'vertical', 'horizontal'} or float, default='horizontal'
How to print a Confusion matrix from Random Forests in Python In general, if you do have a classification task, printing the confusion matrix is a simple as using the sklearn.metrics.confusion_matrix function. As input it takes your predictions and the correct values: from sklearn.metrics import confusion_matrix conf_mat = confusion_matrix (labels, predictions) print (conf_mat) You could consider altering ... python - Sci-kit learn how to print labels for confusion matrix ... You can use the code below to prepare a confusion matrix data frame. labels = rfc.classes_ conf_df = pd.DataFrame (confusion_matrix (class_label, class_label_predicted, columns=labels, index=labels)) conf_df.index.name = 'True labels' The second thing to note is that your classifier is not predicting labels well. how to print confusion matrix in python with labels Code Example import pandas as pd cmtx = pd.DataFrame( confusion_matrix(y_true, y_pred, labels=['yes', 'no']), index=['true:yes', 'true:no'], columns=['pred:yes', 'pred:no ...
