Failure-informed PINNs for a multi-strain SVEIR epidemic model
This paper pairing Failure-Informed PINNs with a Self-Adaptive Importance Sampling (SAIS) refinement strategy, and applying the combination to a nine-equation Susceptible/Vaccinated/Exposed/Infected/Recovered (SVEIR) model that follows three viral strains together with a vaccination compartment, shows an improvement of two to three orders of magnitude.
