Blood Pressure Estimation Using Photoplethysmography Only: Comparison between Different Machine Learning Approaches

Figure 6

(a, b) Overall BP measurement accuracy from the 10-fold cross-validation, separately for the three machine learning algorithms; (c–h) Bland–Altman plots for the BPs estimated from the regression tree, MLR, and SVM. (c), (e), and (g) are for SBP, and (d), (f), and (h) are for DBP. MLR, multiple linear regression; SVM, support vector machine.
