TP = true positives, the number of correctly recognized active compounds;

FN = false negative, the number of active compounds that the model is unable to recognize;

TN = true negative, the number of inactive compounds that successfully recognized by the model;

FP = false positive, the number of inactive compounds that the model is unable to recognize.
