Infection numbers obtained from the reported data (black), the training of the PINN (red) or the NSFD scheme with distinct transmission risk parameter values (blue, cyan, green) from the 78th regarded week (34th calendar week in 2021) for three different assignments of the weighting parameter α (\(\alpha = 0.5, 0.9, 0.95\)). The used training data cover the calendar weeks 10 in 2020 through 52 in 2021 (1st through 96th regarded week)
