Consistency capacity of reservoir computers

Understand

We study the propagation and distribution of information-carrying signals injected in dynamical systems serving as a reservoir computers.

• A multivariate correlation analysis in tailored replica tests reveals consistency spectra and capacities of a reservoir.
• These measures provide a high-dimensional portrait of the nonlinear functional dependence on the inputs.
• For multiple inputs a hierarchy of capacity measures characterizes the interference of signals from each source.
