Conceptual diagram of domain D, biome B, and classified region C.
A temperature-based classifier defines region C. The goal is for C to accurately represent biome B by minimizing both the false positive area (FPA, where C incorrectly includes areas outside B) and the false negative area (FNA, where C fails to include parts of B). This is achieved by minimizing the maximum of FPA and FNA (MFPNA).

Classifier applied to ice cap domain.
Colors represent true positive (green), true negative (blue), false positive (red), false negative (orange), and out-of-domain (white) regions. Basemap from Natural Earth (public domain).

Classifier applied to polar domain.
Colors represent true positive (green), true negative (blue), false positive (red), false negative (orange), and out-of-domain (white) regions. The domain did not include Antarctica and places north of latitude due to missing data, but these regions are expected to lie in the true positive regions and thus not significantly affect misclassified land areas.
