Oct 04, 2020 · Confusion Matrix. Although scikit-learn has a built-in plot_confusion_matrix within its metrics library, Yellowbrick's confusion matrix has additional features that may be of benefit. The argument percent=True will display the percent of true (or the cell divided by the row total). The label_encoder argument will accept a sci-kit learn label encoder or a dictionary

Oct 10, 2018 · Confusion matrix shows the amount of confusion. We use confusion matrices to understand which classes are most easily confused. There are two sets of labels in a confusion matrix of binary (2 class) classification: {POSITIVE, NEGATIVE}- first, the model makes the prediction. It returns the labels 1 (POSITIVE) or 0 (NEGATIVE)
