  4. Abstract:
  5. Coming up with a model which matches biological observations more closely has always been one of the main challenges in the field of artificial neural networks. Lately, an ionic model of reservoir networks containing spiking neurons (ILS-based reservoir network) has been proposed which seems to replicate some of the biological processes we have observed up until now. This paper presents a local learning rule for the ILS-based reservoir inspired by the biological fact that each incoming stimulus causes the formation of new dendritic spines, producing new synapses. This property may result in a higher degree of neuroplasticity, leading to a higher learning capacity. To evaluate the proposed learning rule, which somehow takes the structural plasticity into account, several experiments have been designed that show its stability and its effectiveness on separation property, classification accuracy, and reliability. Several benchmark cases have also been discussed and their results through separation and classification evaluation metrics, demonstrate the superior performance of the ILS-based reservoir network trained by the proposed learning rule compared to the untrained similar network. © 2022, The Author(s), under exclusive licence to Springer-Verlag London Ltd., part of Springer Nature
