Simple Reservoirs with Chain Topology Based on a Single Time-Delay Nonlinear Node

A physical scheme based on a single nonlinear dynamical system with delayed feedback has been recently proposed for Reservoir Computing (RC). In this paper we present a computational implementation of this idea using a simple chain topology with properties derived from its physical counterpart (e.g. the reservoir is defined by two tunable parameters related to feedback- and input-strength terms). An application to time series prediction is described and a comparison with other standard reservoir computing methods is given.
