Final Project for Introduction to Scientific Machine Learning course by Prof. Yeonjong Shin

• Topic: South Korea COVID prediction model by using PINN, SIRVD model

$$ \begin{cases} {dS \over dt} = -{\beta \over N}IS + \sigma R - \alpha S \\ {dI \over dt} = +{\beta \over N}IS - \gamma I - \delta I\\ {dR \over dt} = +\gamma I -\sigma R\\ {dV \over dt} = +\alpha S\\ {dD \over dt} = +\delta I \\ \end{cases} $$

From [6], we get V(t) from totalSecondCnt.
From [5], we get I(t), R(t), D(t), and S(t) from decideCnt-clearCnt-deathCnt,
clearCnt, deathCnt, 5174e+4-I(t)-R(t)-D(t)-V(t), respectively.
