LOO results on MIMIC Database with the best neural network (ResNet + LSTM), since direct SBP/DBP prediction did not predict the entire signal, the first two columns are empty. Errors are expressed in mmHg. PPG refers to the configuration where only the PPG signal is used as input, while ECG refers to the configuration with both PPG and ECG as input signals
