Spectral operator learning for parametric PDEs without data reliance

no code implementations3 Oct 2023 JunHo Choi, Taehyun Yun, Namjung Kim, Youngjoon Hong

In this paper, we introduce the Spectral Coefficient Learning via Operator Network (SCLON), a novel operator learning-based approach for solving parametric partial differential equations (PDEs) without the need for data harnessing.
