We present Lift & Learn, a physics-informed method for learning low-dimensional models for large-scale dynamical systems. The method exploits knowledge of a system's governing equations to identify a coordinate transformation in which the system dynamics have quadratic structure. This transformation is...
Learn Koopman and Transfer operators for Dynamical Systems and Stochastic Processes kooplearn is a Python library designed for learning Koopman or Transfer operators associated with dynamical systems. Given a nonlinear dynamical system xt+1=S(xt), the Koopman operator provides a global linearization of...

Reservoir computing (RC) is a machine learning technique that builds on dynamical systems theory and provides the basis of the team's approach. RC is used to control a type of neural network called a recurrent neural network (RNN). Unlike other machine learning approaches that tune all neural...
We introduce an algebraic analogue of dynamical systems, based on term rewriting. We show that a recursive function applied to the output of an iterated rewriting system defines a formal class of models into which all the main architectures for dynamic machine learning models (including recurrent ne...
