These are the calibration curves for the logistic regression (LR) and Gaussian naive Bayes (GNB) models, where the closer the curve is to the diagonal line, the more accurate the model is.A is the calibration curve for the training set of the LR model; B is the calibration curve for the test set of the LR model; C is the calibration curve for the training set of the GNB model; And D is the calibration curve for the test set of the GNB model.
