Synchronization between two linearly coupled reservoir computers

Abstract

Reservoir computing, using a model-free algorithm, has drawn considerable attention in the past few years. In this work, we use a reservoir computer to reconstruct the attractor of its learned chaotic system. We present a form of interaction between two reservoir computers inspired by the diffusion coupling of oscillators. By mixing the readout of two reservoir computers with an appropriate coupling strength, we present the complete synchronization of reservoir computers. Numerical experiments are performed to verify the theory.
