Stabilizing Machine Learning Prediction of Dynamics: Noise and Noise-inspired Regularization

1 code implementation9 Nov 2022 Alexander Wikner, Joseph Harvey, Michelle Girvan, Brian R. Hunt, Andrew Pomerance, Thomas Antonsen, Edward Ott

In this article, we systematically examine the technique of adding noise to the ML model input during training to promote stability and improve prediction accuracy.

A Meta-learning Approach to Reservoir Computing: Time Series Prediction with Limited Data

no code implementations7 Oct 2021 Daniel Canaday, Andrew Pomerance, Michelle Girvan

Recent research has established the effectiveness of machine learning for data-driven prediction of the future evolution of unknown dynamical systems, including chaotic systems.

Model-Free Control of Dynamical Systems with Deep Reservoir Computing

no code implementations5 Oct 2020 Daniel Canaday, Andrew Pomerance, Daniel J Gauthier

We propose and demonstrate a nonlinear control method that can be applied to unknown, complex systems where the controller is based on a type of artificial neural network known as a reservoir computer.

Combining Machine Learning with Knowledge-Based Modeling for Scalable Forecasting and Subgrid-Scale Closure of Large, Complex, Spatiotemporal Systems

no code implementations10 Feb 2020 Alexander Wikner, Jaideep Pathak, Brian Hunt, Michelle Girvan, Troy Arcomano, Istvan Szunyogh, Andrew Pomerance, Edward Ott

We consider the commonly encountered situation (e. g., in weather forecasting) where the goal is to predict the time evolution of a large, spatiotemporally chaotic dynamical system when we have access to both time series data of previous system states and an imperfect model of the full system dynamics.

Forecasting Chaotic Systems with Very Low Connectivity Reservoir Computers

no code implementations1 Oct 2019 Aaron Griffith, Andrew Pomerance, Daniel J. Gauthier

We explore the hyperparameter space of reservoir computers used for forecasting of the chaotic Lorenz '63 attractor with Bayesian optimization.
