Indicators for evaluating algorithm performance.

Evaluation criteria	Calculation method
Accuracy	Accuracy = (TP + TN)/(TP + TN + FP + FN)
Precision	Precision = TP/(TP + FP)
Specificity	Specificity = TN/(TN + FP)
False positive rate	FPR = FP/(FP + TN)
Recall	Recall = TP/(TP + FN)
F1-score	F1-score = 2  precision  recall/(precision + recall)
