Investigation of plasticity in off-resonant delay-coupled reservoir computing — •Jonas Naujoks1, Felix Köster1, and Kathy Lüdge2 — 1Institute for Theoretical Physics, Technische Universität Berlin, 10559 Berlin, Germany — 2Institute of Physics, Technische Universität Ilmenau, Weimarer Str. 25, 98693 Ilmenau, Germany
We analyse the effect of neuronal plasticity on the performance of a delay-based reservoir computer modelled by a generic oscillator with self-feedback. The memory capacity and task-specific performance are investigated in the case of non-resonant delay-clock-cycle configurations. By modifying the temporal multiplexing of the input, the responsiveness of the virtual nodes is maximised while promoting individual decorrelation. The training is done in an unsupervised manner. The effect on the task-specific performance is investigated, while we additionally demonstrate that the memory capacity can be tuned.
