TABLE II. Validation of Synthesized Pre-Ictal Samples of Scalp EEG Data Using Different Combinations of Synthesized and Real Data for Training and Testing on CESP. Synthesized Data Generated From the DCGAN trained on the CHB-MIT dataset. The Comparison of Results of i) Test & Train on Real Data (TRTR) and ii) Train on Synthetic Data & Test on Real Data (TSTR), Shows That the Synthetic Data Has Fully Captured the Correlation Between the Features of Data and the Labels. Legends: TRTR = Train & Test on Real Data, TSTR = Train on Synthesized Data & Test on Real Data, TRTS = Train on Real Data & Test on Synthesized Data, TSTS = Train & Test on Synthesized Data, Sen = Sensitivity, Spec = Specificity, Acc = Accuracy.
