Enhancing reservoir predictions of chaotic time series by incorporating delayed values of input and reservoir variables — •Luk Fleddermann^1,2 and Ulrich Parlitz^1,2 — ¹Max Planck Institute for Dynamics and Self-Organization, Göttingen, Germany — ²Institute for the Dynamics of Complex Systems, University of Göttingen, Germany

Chaotic time series can be predicted using linear readouts of driven reservoir dynamics. In the applied case, typically only time series of incomplete measurements, i.e. partial observations of the dynamical state, are available. We compare the performance of reservoir computing for time series predictions with complete and partial system state knowledge. By combining delayed values of input and reservoir variables, we increase the mean time length of valid predictions for partial observations of the dynamical state.
