Table 1: Symbols and definitions of the \(D[GBI]ej\) descriptors present in the PTML-MLP model. When assessing the statistical quality (training set) and predictive power (test set) of the PTML-MLP model, we can say that \(Acc=84.48\%\) was achieved in the training set while \(Acc=80.26\%\) was reached in the test set. Also, other statistical indices such as \(Sn\), \(Sp\), and \(MCC\) support the good performance of our PTML-MLP model (Table 2).
