Pharmacokinetics model: Schematic of the PINNs algorithm for predicting the unknown term h(t; θ2) and the values of parameters simultaneously.
Here, u(t; θ1) is a vector that contains all three output states. Unlike the X-TFC network, PINN requires back-propagation, which is the expensive computational component.
