摘要:In this paper, the one-dimensional PDE model is extended to the two-dimensional model, so that the COVID-19 prediction model which is in line with the actual two-dimensional regional distribution can be established. Based on the prediction model, the undetermined parameters in the differential equation model are inversed by using the spontaneous perturbation stochastic gradient algorithm (SPSA) according to the actual number of infections, so as to accurately predict the number of infections in the future. The effectiveness of this model is also confirmed by the recent outbreak of local epidemic data in China.
