The confusion matrix is a way of tabulating the number of misclassifications, i.e., the number of predicted classes which ended up in a wrong classification bin based on the true classes. While sklearn.metrics.confusion_matrix provides a numeric matrix, I find it more useful to generate a 'report' using the following:
