Physics constrained deep learning
WebbPhysics-informed neural networks (PINNs) are a type of universal function approximators that can embed the knowledge of any physical laws that govern a given data-set in the learning process, and can be described by partial differential equations (PDEs). They overcome the low data availability of some biological and engineering systems that … WebbSecond, these sample points are used as inputs of the PINN. Minimizing the PDE residuals measured at these sample points during the optimization process enforces the satisfaction of physics constraints, i.e., g c in Eq. (1).Third, the flow variables (u, v, p) outputted from the surrogate model are used to compute the objective function values.Back-propagation …
