Abstract

Abstract Successful implementation of spiking neural networks onto CMOS‐Molecular (CMOL) architecture has already been proposed, but the ability of dynamic learning has not yet been addressed. Here, we propose a spiking neural topology with spike‐timing‐dependent learning ability and provide its basic building blocks that are easily mapped onto CMOL architecture. The learning method modifies state of synaptic switches, using spatially and temporally local information which is available at the synapse when state modification is performed. The performance of the proposed topology is analyzed with regards to pre‐ and post‐synaptic spike timing, and simulation results are provided for a synapse with spike‐timing‐dependent plasticity properties. Furthermore, its performance as spike‐timing correlation learning and synchrony detection in a small feed‐forward network is demonstrated as a case example. Copyright © 2010 John Wiley & Sons, Ltd.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
