Invertible Koopman neural operator for data-driven modeling of partial differential equations
Yuhong Jin, Andong Cong, Lei Hou +5
Koopman operator theory is a popular candidate for data-driven modeling because it provides a global linearization representation for nonlinear dynamical systems. However, existing…
