Reservoir computing with a single time-delay autonomous Boolean node

© 2015 American Physical Society. We demonstrate reservoir computing with a physical system using a single autonomous Boolean logic element with time-delay feedback. The system generates a chaotic transient with a window of consistency lasting between 30 and 300 ns, which we show is sufficient for reservoir computing. We then characterize the dependence of computational performance on system parameters to find the best operating point of the reservoir. When the best parameters are chosen, the reservoir is able to classify short input patterns with performance that decreases over time. In particular, we show that four distinct input patterns can be classified for 70 ns, even though the inputs are only provided to the reservoir for 7.5 ns.N.D.H. and D.J.G. gratefully acknowledge financial support from the U.S. Army Research Office through Grant No. W911NF-12-1-0099.
