An adjoint-free algorithm for conditional nonlinear optimal perturbations (CNOPs) via sampling

no code implementations1 Aug 2022 Bin Shi, Guodong Sun

In this paper, we propose a sampling algorithm based on state-of-the-art statistical machine learning techniques to obtain conditional nonlinear optimal perturbations (CNOPs), which is different from traditional (deterministic) optimization methods. 1 Specifically, the traditional approach is unavailable in practice, which requires numerically computing the gradient (first-order information) such that the computation cost is expensive, since it needs a large number of times to run numerical models.
