1 Correction to: Comput Mech https://doi.org/10.1007/s00466-020-01894-2

The original article was published with errors in some sentences. The correct sentences are provided in this correction.

The word “rate” in the sentence “It follows that \(\beta (t)/\mu (t)\) is the effective reproduction rate: the total number...” under the section “2 The compartmental model of infectious disease dynamics” should read as “number”.

The sentence “The F-test is achieved through the following algorithm” below the equation 20 should read as “The F-test is achieved through the application of Algorithm 2”.

Also, under the section “6.1 Systemidentification and ODE-constrained Optimization”, the word “rate” in the sentence “...rapid decline of the effective reproduction rate, r0(t).” in the third paragraph should read as number”. The word “East” in the sentence “By contrast, Washtenaw County, about 50 km to the East, but” in the fourth paragraph should read as “west”.

Under the section “6.2 Deep and Bayesian neural networks” the word “Appendix” in the sentence “Regions are given in Appendix...” in fourth paragraph should read as “Appendices”

In the fifth paragraph, the word “rate” in the sentence “The effective reproduction rate r0(t)...” should read as “number” and the word “Appendix” in the sentence “The regional results in Appendix “DNN” should read as “Appendices”.

The word “rate” in the caption of Fig. 6 “Parameters of time-dependent SIRD coefficients, \(\beta (t)\), \(\mu (t)\), \(\alpha (t)\), and the effective reproduction rate, r0(t), for Regions 1–8 (see Fig. 1) of Michigan” should read as “number”.

In the seventh paragraph, the word “rate” in the sentence “...effective reproduction rate r0(t)” should read as “number”.

The Eqs. 43, 44 and 45 was published incorrectly. The correct equations are provided below.

$$\begin{aligned} {\mathcal {D}}_{\text {s}} (\hbox {t})= & {} \uptheta 16 + \uptheta 17\hbox {t} + \uptheta 18\hbox {t}2 + \uptheta 19\hbox {t}3 \end{aligned}$$
(43)
$$\begin{aligned} {\mathcal {D}}_{\text {i}} (\hbox {t})= & {} \uptheta 20 + \uptheta 21\hbox {t} + \uptheta 22\hbox {t}2 + \uptheta 23\hbox {t}3 \end{aligned}$$
(44)
$$\begin{aligned} {\mathcal {D}}_{\text {r}} (\hbox {t})= & {} \uptheta 24 + \uptheta 25\hbox {t} + \uptheta 26\hbox {t}2 + \uptheta 27\hbox {t}3 \end{aligned}$$
(45)

The word “rate” under the section “7.3 Results of system identification of two dimensional SIRDmodel with diffusion” in the fourth line should read as “number” and the sentence “While the preliminary nature of these warrants caution...” should read as “While the preliminary nature of these results warrants caution..”.

The word “open” in the caption of Fig. 16 “Regions 1–8: Time-dependent coefficients identified by DNNs, where an increased infection rate after the open (O) of lockdown on June 1st is observed” should read as “opening”.

The word “open” in the caption of Fig. 18 “Regions 1–8: Time-dependent coefficients identified by BNNs, where an increased infection rate after the open (O) of lockdown on June 1st is observed. Bands correspond to ± standard deviation over the mean” should read as “opening”.
