Abstract
A technology for obtaining a heart rate from a photoplethysmogram (PPG) signal. In one example, an artificial neural network model can be trained to predict a heart rate using a training dataset containing PPG data. The artificial neural network model can include a series of convolutional layers to remove artifacts from a PPG signal, a fast Fourier transform (FFT) layer to convert the PPG signal to PPG frequency representations, and a dense layer to decode the PPG frequency representations to heart rate predictions. After training the artificial neural network model, PPG data generated by a pulse oximeter monitor can be obtained, and the PPG data can be input to the artificial neural network model. The artificial neural network model outputs a heart rate prediction, wherein the heart rate prediction represents the heart rate obtained from the PPG signal.
