Classification of the predictions: Illustrations.

(a) Illustration of the standard pixels classification derived from the comparison between prediction and reality (TP, FP, FN and TN, together forming the confusion matrix) from a sub-sample of our predicted test set in the region of Bata, Equatorial Guinea. (b) Confusion matrices computed for three distinct scenarios (defined in section Performances along probability threshold value). It comes with an illustration of the binary prediction (red shapes) performed for the corresponding T value, in the region of New Netim (Nigeria). Note that figures are computed for the whole test set, contrary to the sample images that aim to illustrate the effect of the T value variation on a relevant area.
