PPGBP dataset

PPGBP dataset: The short-recorded PPG dataset collected and shared by Liang et al. [4]. It contains 219 subjects, with one BP reading followed by three PPG segments with a duration of 2.1 seconds each. Thus, it is the smallest set in the number of segments (613) but with a relatively high number of subjects. The original sampling frequency of 1000 Hz was resampled at 125 Hz. We conducted a 5-fold CV to partition the data once it was preprocessed. [4] Liang, Y., Chen, Z., Liu, G. & Elgendi, M. PPG-BP database (2018).
