Fig. 1From: Using the spike protein feature to predict infection risk and monitor the evolutionary dynamic of coronavirusSchematic framework of machine learning. First, feature representations from three feature descriptors are obtained. Second, the RF method is used to train and test the dataset and make predictions for cross-species transmission of coronavirus.
