... reconstruction which can overcome the hurdles of the above methods. Design/methodology/approach A multifidelity strategy leveraging PINN and a nonlinear information fusion (NIF) algorithm is proposed. Plentiful low-fidelity data are generated from the predictions of a PINN which is constructed purely using...
