Formulas of the four evaluation criteria.

	Formula
ACC	$(N_{a a} + N_{b b} + N_{c c}) / \sum_{i, j \in [a, b, c]} N_{i j}$
Macro-average	$[\frac{N_{a a}}{\sum_{j \in [a, b, c]} N_{a j}} + \frac{N_{b b}}{\sum_{j \in [a, b, c]} N_{b j}} + \frac{N_{c c}}{\sum_{j \in [a, b, c]} N_{c j}}] / 3$
Mean-OVA-AUC	[AUC_{a vs.all} + AUC_{b vs.all} + AUC_{c vs.all}]/3
Multi-class AUC	$[\hat{A} (a, b) + \hat{A} (a, c) + \hat{A} (b, c)] / 3$
