Performance judgment criteria of the proposed model.

Parameter	Formulation
Sensitivity (Sn)	$\frac{\text{TP}}{\text{TP}+\text{FN}}$
Specificity (Sp)	1-FPR or TN/TN + FP
Accuracy (Acc)	$\frac{\text{TN}+\text{TP}}{\text{TN}+\text{FP}+\text{TP}+\text{FN}}$
Area under ROC curve (AUC)	Sn + Sp/2
Matthews correlation coefficient (MCC)	$\frac{\text{TP}/N-S\times P}{\sqrt{P\times S\times \left(1-S\right)\times }\left(1-P\right)}$
Connectivity-area-length (CAL)	f(C, A, L) = C × A × L
