Abstract

The embodiment of the invention discloses a parameter fitting method of an infectious disease propagation model, a device, a storage medium and electronic equipment; and the method comprises the steps: obtaining real propagation data representing the actual propagation condition of a virus, and obtaining model prediction data through a multi-node infectious disease propagation model; evaluating loss errors between model prediction data and real propagation data through a loss function, and correcting all parameters of the infectious disease propagation model through a back propagation algorithm based on the loss errors to obtain final parameters; and thus the BP-based fitting algorithm utilizes the idea of gradient descent, the fitting speed of the parameters of the infectious disease propagation model can be increased, and the model training time is shortened.

Description

technical field [0001] The present application relates to the field of epidemic forecasting, in particular to a parameter fitting method, device, storage medium and electronic equipment of an infectious disease propagation model. Background technique [0002] The large-scale spread of viruses often brings huge panic and incalculable economic losses to the society. Various viruses, including computer viruses and biological viruses, spread rapidly to all parts of the world through the Internet. The Covid-19 (new coronavirus) that broke out in December 2019 spread to countries all over the world in just a few months, infecting millions of people and causing immeasurable economic losses. Therefore, the research on the virus transmission model is indispensable. By modeling the transmission model, the path and mode of virus transmission can be effectively analyzed and corresponding responses can be made. [0003] Existing virus transmission models include SEIR, etc., among which ...
