Fig. 6 |. Hemodynamic classification.

a, Confusion matrix of model predictions, grouped by hemodynamic condition (quadrant on BP vs SVR axis). b, c, Receiver operating characteristic curves (b) and precision-recall curves (c) for all hemodynamic state predictions (one vs all) colored by the quadrants outlined in Fig. 1c, and highlighted micro-average curve in black. Area under the curve values for receiver operating characteristic curves are: baseline = 0.96, exercise = 0.98, sauna = 0.93, cold pressor/breath hold = 0.98, surgical pressors = 1.0. Area under the curve values for precision-recall curves are (baseline = 0.82, exercise = 0.98, sauna = 0.80, cold pressor/breath hold = 0.73, surgical pressors = 0.93).
