Error analysis for finite element operator learning methods for solving parametric second-order elliptic PDEs

no code implementations27 Apr 2024 Youngjoon Hong, Seungchan Ko, Jaeyong Lee

In this paper, we provide a theoretical analysis of a type of operator learning method without data reliance based on the classical finite element approximation, which is called the finite element operator network (FEONet).

Finite Element Operator Network for Solving Parametric PDEs

no code implementations9 Aug 2023 Jae Yong Lee, Seungchan Ko, Youngjoon Hong

Partial differential equations (PDEs) underlie our understanding and prediction of natural phenomena across numerous fields, including physics, engineering, and finance.

Convergence analysis of unsupervised Legendre-Galerkin neural networks for linear second-order elliptic PDEs

no code implementations16 Nov 2022 Seungchan Ko, Seok-Bae Yun, Youngjoon Hong

In this paper, we perform the convergence analysis of unsupervised Legendre--Galerkin neural networks (ULGNet), a deep-learning-based numerical method for solving partial differential equations (PDEs).

A novel approach for wafer defect pattern classification based on topological data analysis

no code implementations19 Sep 2022 Seungchan Ko, Dowan Koo

In semiconductor manufacturing, wafer map defect pattern provides critical information for facility maintenance and yield management, so the classification of defect patterns is one of the most important tasks in the manufacturing process.
