WebSep 23, 2024 · This work proposes a novel PINN-based architecture that is amenable to control problems and able to simulate for longer-range time horizons that are not fixed … WebSep 23, 2024 · To this end, we develop a parareal physics-informed neural network (PPINN), hence decomposing a long-time problem into many independent short-time problems supervised by an inexpensive/fast coarse-grained (CG) solver. In particular, the serial CG solver is designed to provide approximate predictions of the solution at discrete …
