As shown in this figure, 4 MR image modalities are input to the ANN to predict T2WI. Note that the MR modalities are normalized to their brain mean values before feeding to the ANN.
A Correct Classification Fraction versus epochs for the optimal ANN (4∶3∶3∶1) using
83 slices of 12 patients with 12 folds.
Note the termination epoch is around 35, which is corresponding to 10% of CCF curve plateau. 2-B: Area Under Correct Classification Fraction (AUCCF) curve versus number of neurons in the second hidden layer. As shown in this figure, AUCCF is maximum for three neurons in the second hidden layer.
