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). Figshare https://doi.org/10.6084/m9.figshare.5459299.

PPGBP数据集：本数据集为Liang等人[4]采集并共享的短时光电容积脉搏波（Photoplethysmography，PPG）数据集，共包含219名受试者。每名受试者对应1次血压（Blood Pressure，BP）测量读数，以及三段时长均为2.1秒的PPG信号片段。因此，该数据集的信号片段总数（共613段）为同类公开数据中较少的，但受试者数量相对较多。原始采样频率为1000Hz，后续被重采样至125Hz。数据经预处理后，我们采用5折交叉验证（5-fold Cross Validation，5-fold CV）对数据集进行划分。[4] Liang Y, Chen Z, Liu G, Elgendi M.
