Attractor reconstruction with reservoir computers: The effect of the reservoir's conditional Lyapunov exponents on faithful attractor reconstruction

no code implementations30 Dec 2023 Joseph D. Hart

Reservoir computing is a machine learning framework that has been shown to be able to replicate the chaotic attractor, including the fractal dimension and the entire Lyapunov spectrum, of the dynamical system on which it is trained.

Reservoir Computing with Noise

no code implementations28 Feb 2023 Chad Nathe, Chandra Pappu, Nicholas A. Mecholsky, Joseph D. Hart, Thomas Carroll, Francesco Sorrentino

For all the cases we examined, we found that a good remedy to noise is to low-pass filter the input and the training/testing signals; this typically preserves the performance of the reservoir, while reducing the undesired effects of noise.

Time-shift selection for reservoir computing using a rank-revealing QR algorithm

no code implementations29 Nov 2022 Joseph D. Hart, Francesco Sorrentino, Thomas L. Carroll

Reservoir computing, a recurrent neural network paradigm in which only the output layer is trained, has demonstrated remarkable performance on tasks such as prediction and control of nonlinear systems.

Time Shifts to Reduce the Size of Reservoir Computers

no code implementations3 May 2022 Thomas L. Carroll, Joseph D. Hart

Additionally, the need to create and connect large numbers of nonlinear nodes makes it difficult to design and build analog reservoir computers that can be faster and consume less power than digital reservoir computers.

Machine Learning Link Inference of Noisy Delay-coupled Networks with Opto-Electronic Experimental Tests

no code implementations29 Oct 2020 Amitava Banerjee, Joseph D. Hart, Rajarshi Roy, Edward Ott

To achieve this, we first train a type of machine learning system known as reservoir computing to mimic the dynamics of the unknown network.

Critical Switching in Globally Attractive Chimeras

1 code implementation18 Nov 2019 Yuanzhao Zhang, Zachary G. Nicolaou, Joseph D. Hart, Rajarshi Roy, Adilson E. Motter

We report on a new type of chimera state that attracts almost all initial conditions and exhibits power-law switching behavior in networks of coupled oscillators.

Topological Control of Synchronization Patterns: Trading Symmetry for Stability

1 code implementation8 Feb 2019 Joseph D. Hart, Yuanzhao Zhang, Rajarshi Roy, Adilson E. Motter

Symmetries are ubiquitous in network systems and have profound impacts on the observable dynamics.
