Independent validation has been performed of the mining data set using control points. For that, we draw 1,000 random samples stratified between two classes: mine and no-mine. The overall accuracy calculated from the control points was 88.3%, Kappa 0.77, F1 score 0.87, producer's accuracy of class mine 78.9 % and user's accuracy of class mine 97.2 %.
