Dataset partition for each patient (A) and flowchart of blood pressure estimation model construction and evaluation (B). RMSEDTR, RMSESVR, RMSEAdaboostR, and RMSERFR represents the root mean square error between the reference and the estimated blood pressure values by the DTR, SVR, AdaboostR, and RFR, respectively. RMSE, root-mean-square error; DTR, decision tree regression; SVR, support vector machine regression; AdaboostR, adaptive boosting regression; RFR, random forest regression.
