Data fitting and inference of the time-dependent parameters by TDINN algorithm for the local outbreaks in Hainan and Xinjiang.

Abstract

(a)-(c) and (f)-(h) show the fitting results in Hainan and Xinjiang, respectively, where the cyan solid dots represent the daily reported data from communities, the purple solid dots represent the daily reported data from quarantined population and the red solid dots represent the daily reported data, green solid curves represent the best fitting results by TDINN, the dashed curves represent the corresponding solution curves after substituting various combinations of the family of functions (4) and (5) into model (1). (d)-(e) and (i)-(j) show the inference and fitting results of the time-dependent contact rate c(t) and quarantined rate q(t) in Hainan and Xinjiang, respectively, where the magenta pentagrams represent the inference results of c(t) and q(t) by TDINN and the solid curves represent the fitting results of c(t) and q(t) based on different functions in (4) and (5).</p
