Modelling Arterial Pressure Waveforms Using Gaussian Functions and Two-Stage Particle Swarm Optimizer
Figure 6
Means and standard deviations (SDs) of the computation time for the four methods (Nelder-Mead, MPSO, DMS-PSO, and TSPSO). The results from 20 volunteers are given at different mean absolute error (MAE) levels (10%, 8%, 6%, 4%, 3%, 2%, and 1.5%), (a) for CAPW signal and (b) for RAPW signal. The SDs of computation time at all MAE levels are relatively small. “Inf.” indicates that the target MAE level can not be achieved even with extremely large maximum number of function evaluations max_FEs (100000).
