Left: Mean absolute error (MAE) of subjects that showed a clear improvement before vs. after fine tuning using remote photoplethymographic (rPPG) data. Right: Comparison of the MAE for different personalization strategies using the first 20% of the test subject’s data vs. randomly drawn data for AlexNet (a) and ResNet (b).
