Extended Data Fig. 10: The impact of the number of simulations performed used for training the GPE on the resultant R2score and ISE along with the resultant total effects of CV.

a. is for GPEs with the output as QRSd on the 30 tissue-level parameters. b. is for GPEs with the output as QRSd on 31 parameters including 30 ECG electrodes’ locations and CV.
