Estimation of PWV on a hold-out test set containing 1312 virtual subjects using the recurrent neural network, with different levels of added white noise.
Estimated against measured PWV with the linear regression line in red, the coefficient of determination, r2, and the p-value (top). Corresponding Bland-Altman plots (bottom). SNR: signal to noise ratio.
