Data-Driven Observability Decomposition with Koopman Operators for Optimization of Output Functions of Nonlinear Systems

Shara Balakrishnan, Aqib Hasnain, Robert Egbert +1

When complex systems with nonlinear dynamics achieve an output performance objective, only a fraction of the state dynamics significantly impacts that output. Those minimal state d…

Data-Driven Operator Theoretic Methods for Phase Space Learning and Analysis

Sai Pushpak Nandanoori, Subhrajit Sinha, Enoch Yeung

This paper uses data-driven operator theoretic approaches to explore the global phase space of a dynamical system. We defined conditions for discovering new invariant subspaces in…

The Effect of Sensor Fusion on Data-Driven Learning of Koopman Operators

Shara Balakrishnan, Aqib Hasnain, Rob Egbert +1

Dictionary methods for system identification typically rely on one set of measurements to learn governing dynamics of a system. In this paper, we investigate how fusion of output m…

On Few Shot Learning of Dynamical Systems: A Koopman Operator Theoretic Approach

Subhrajit Sinha, Umesh Vaidya, Enoch Yeung

In this paper, we propose a novel algorithm for learning the Koopman operator of a dynamical system from a \textit{small} amount of training data. In many applications of data-driv…

Prediction of fitness in bacteria with causal jump dynamic mode decomposition

Shara Balakrishnan, Aqib Hasnain, Nibodh Boddupalli +3

In this paper, we consider the problem of learning a predictive model for population cell growth dynamics as a function of the media conditions. We first introduce a generic data-d…
