A spatiotemporal deep learning model for forecasting the development of sudden epidemics modified by historical meteorological data

Resumen de: IE20230427U1

This invention discloses a spatiotemporal deep learning model for forecasting the development of sudden epidemics, taking into consideration meteorological factors. The method formulates the short-term prediction problem of regional new COVID-19 cases as a predictive technical issue involving multidimensional, gridded spatiotemporal sequences for both input and prediction targets. To address this, a ConvLSTM spatiotemporal deep model is constructed for predicting COVID-19 case numbers. Furthermore, the model is enhanced by considering the modifying effects of meteorological elements, creating a comprehensive spatiotemporal model called the Meteor-ConvLSTM model that integrates historical meteorological factors. This spatiotemporal model produces timely, downscaled, and high-resolution prediction results. This invention is characterized by high predictive accuracy and strong practicality, making it useful for guiding relevant authorities in understanding the epidemic situation and adjusting decision-making strategies. <Figure 1>
