Abstract

Techniques and mechanisms for servicing a search query using a spiking neural network. In an embodiment, a spiking neural network receives an indication of a first context of the search query, wherein a set of nodes of the spiking neural network each correspond to a respective entry of a repository. One or more nodes of the set of nodes are each excited to provide a respective cyclical response based on the first context, wherein a first cyclical response is by a first node. Due at least in part to a coupling of the excited nodes, a perturbance signal, based on a second context of the search query, results in a change of the first resonance response relative to one or more other resonance responses. In another embodiment, data corresponding to the first node is selected, based on the change, as an at least partial result of the search query.

receive, at a first set of nodes of the spiking neural network, a first one or more spike trains which indicate a first context of a context-based search;
receive, at a second set of nodes of the spiking neural network, a second one or more spike trains from the first set of nodes, wherein each node of the second set of nodes corresponds to a respective entry of a repository, wherein a first node of the second set of nodes corresponds to a first entry of the repository, wherein one or more nodes of the second set of nodes each exhibits a respective cyclical response based on the second one or more spike trains, wherein the one or more nodes of the second set is a subset of all nodes of the second set, and wherein the subset includes the first node;
detect the respective cyclical responses by the one or more nodes of the second set of nodes;
identify the one or more nodes of the second set of nodes based on a detection of the cyclical responses;
