ROC curves corresponding to different dimensions of hidden layers. (a) The dimension of the hidden layer of the encoder = (8, 5, 4) (AUC = 0.83). (b) The dimension of the hidden layer of the encoder = (8, 6, 4) (AUC = 0.69). (c) The dimension of the hidden layer of the encoder = (8, 7, 4) (AUC = 0.89).
