Wavelet-based multiscale proper generalized decomposition
Comptes Rendus. Mécanique, 2018 Separated representations at the heart of Proper Generalized Decomposition are constructed incrementally by minimizing the problem residual. However, the modes involved in the resulting decomposition do not exhibit a clear multi-scale character. In order to recover a multi-scale description of the solution within a separated representation framework ...

Application of the Proper Generalized Decomposition to Solve Magnetoelectric Problem [PDF]
IEEE Transactions on Magnetics, 2018 Among the model order reduction techniques, the proper generalized decomposition (PGD) has shown its efficiency to solve a large number of engineering problems. In this paper, the PGD approach is applied to solve a multi-physics problem based on a magnetoelectric device.

A proper generalized decomposition approach for optical flow estimation [PDF]
Mathematical Methods in the Applied Sciences, 2020 This paper introduces the use of the proper generalized decomposition (PGD) method for the optical flow (OF) problem in a classical framework of Sobolev spaces, ie, optical flow methods including a robust energy for the data fidelity term together with a quadratic penalizer for the regularization term.

Least-Squares Proper Generalized Decompositions for Weakly Coercive Elliptic Problems [PDF]
SIAM Journal on Scientific Computing, 2017 Summary: Proper generalized decompositions (PGDs) are a family of methods for efficiently solving high-dimensional partial differential equations (PDEs), which seek to find a low-rank approximation to the solution of the PDE a priori. Convergence of PGD algorithms can only be proven for problems which are continuous, symmetric, and strongly coercive ...
