Physical reservoir replication using small-scale digital calibration reservoir

Abstract

In this study, we propose a technique for replicating physical reservoirs using a small-scale digital calibration reservoir. Recently, physical reservoirs, which comprise the physical systems for reservoir computing and computational methods for time-series pattern recognition, have attracted considerable attention. However, replicating physical reservoirs is challenging because of the individual variations that occur when physical systems are used. We introduce a small-scale digital reservoir that absorbs individual variations, compensates for them, and successfully replicates the performance of a physical reservoir.
