a Probability along core Sections N31–1. The probability of each facies in each data point is visualized in bars and projected to a heatmap above (the deeper the blue, the higher the probability). b The maximum probability for each data point is plotted along with the core image. For abbreviations, refer to Fig. 1. c Bi-plots of (1) distribution of the maximum probability in the groups of correct and incorrect classifications and (2) error rate for each interval of the maximum probability in the test set.
