Physics-Guided Dimension Reduction for Simulation-Free Operator Learning of Stiff Differential-Algebraic Systems
Huy Hoang Le, Haoguang Wang, Christian Moya +2
Neural surrogates for stiff differential-algebraic equations (DAEs) face two barriers: soft-constraint methods leave algebraic residuals that stiffness amplifies into errors, and h…

Efficient streaming dynamic mode decomposition
Aditya Kale, Marcos Netto, Xinyang Zhou
We propose a reformulation of the streaming dynamic mode decomposition method that requires maintaining a single orthonormal basis, thereby reducing computational redundancy. The p…

Participation Factors for Nonlinear Autonomous Dynamical Systems in the Koopman Operator Framework
Kenji Takamichi, Yoshihiko Susuki, Marcos Netto
We devise a novel formulation and propose the concept of modal participation factors to nonlinear dynamical systems. The original definition of modal participation factors (or simp…
