Researchers have developed a new kernel learning approach using cokriging to solve nonlinear partial differential equations (PDEs). This method leverages empirical information from multifidelity simulations to fit a differentiable non-stationary kernel to low-fidelity data. The approach then derives a high-fidelity kernel and mean, which are integrated into a Gaussian process framework for solving PDEs, demonstrating effectiveness on the Burgers' equation. AI
