Daily ahead forecast of confirmed COVID-19 cases by the developed PRC simulator. (a) Comparison between the four prefectures in Japan; Hokkaido, Tokyo, Osaka and Fukuoka, in which the readout was sequentially trained using the latest data. Real lines represent preprocessed actual values, while dotted lines depict their corresponding forecasts. (b) Transition of daily confirmed COVID-19 cases (blue line), its forecast (red line), and the error between them (green line). Top, middle, and bottom rows show the results in which the readout was trained for periods (blue area) of 30, 60, and 120Â days, respectively.
