New framework integrates functional priors into Bayesian PINN inversion

By PulseAugur Editorial · [2 sources] ·

Researchers have developed a new framework called fpBPINN to integrate functional priors into Bayesian inversion problems solved with physics-informed neural networks (PINNs). This framework addresses the challenge of defining prior distributions in function space rather than the typical weight space of neural networks. The study introduces two methods, FPI-BPINN and fParVI-PINN, and demonstrates their effectiveness in seismic traveltime tomography and Darcy-flow permeability inversion, showing accurate posterior distribution estimation.
