Tuning the activation function to optimize the forecast horizon of a reservoir computer

no code implementations20 Dec 2023 Lauren A. Hurley, Juan G. Restrepo, Sean E. Shaheen

By using different functions from this set, and by modifying their parameters, we explore whether the entropy of node activation levels or the curvature of the activation functions determine the predictive ability of the reservoirs.

Detecting disturbances in network-coupled dynamical systems with machine learning

no code implementations24 Jul 2023 Per Sebastian Skardal, Juan G. Restrepo

Identifying disturbances in network-coupled dynamical systems without knowledge of the disturbances or underlying dynamics is a problem with a wide range of applications.

Suppressing unknown disturbances to dynamical systems using machine learning

no code implementations19 Jun 2023 Juan G. Restrepo, Clayton P. Byers, Per Sebastian Skardal

In this Letter, we present a model-free method to identify and suppress an unknown disturbance to an unknown system based only on previous observations of the system under the influence of a known forcing function.
