“…Fourth, the size of the dataset imposed a limitation on providing a separate and independent test dataset to validate the accuracy of the model. A larger database would provide the flexibility to set aside a portion of the data solely for testing purposes and offer a larger training set for the network that can ultimately increase the accuracy of the estimation, as was found in some previous studies such as the ones in [ 18 ] and [ 19 ], where a larger dataset was used. However, there could be other reasons behind their reported better performance, such as: Reference blood pressure values were taken invasively, whereas, in our study, these values are collected through noninvasive methods.…”

“…However, there could be other reasons behind their reported better performance, such as: Reference blood pressure values were taken invasively, whereas, in our study, these values are collected through noninvasive methods. In [ 18 ], because of the large dataset, the authors could afford to apply a BP range constraint, meaning that, whenever the output was beyond a certain threshold, it was eliminated and not considered for performance evaluation. The input in those studies was based on segmented windows of the collected data with overlaps.…”

“…A BP estimation model was developed using the receptive field parallel attention shrinkage network to increase the effectiveness of feature extraction from PPG signals. The mean absolute errors (MAEs) ± SDs for the estimated SBP and DBP were 1.63 ± 2.43 and 2.26 ± 4.04 mmHg, respectively [13]. Li et al proposed a blood pressure estimation method, which can be calibrated with reference inputs rather than with retraining.…”
