Abstract

See full text

Hierarchical routing for two-way information flow and structural plasticity in a neural network is provided. In one embodiment the network includes multiple core modules, wherein each core module has a plurality of incoming connections with predetermined addresses. Each core module also has a plurality of outgoing connections such that each outgoing connection targets an incoming connection in a core module among the multiple core modules. The network also has a routing system that selectively routes signals among the core modules based on a reconfigurable hierarchical organization of the core modules. The network approximates a fully connected network such that each outgoing connection on any core module can target and reach any incoming connection on any core module without requiring a fully connected network. The routing system provides two-way information flow between neurons utilizing hierarchical routing.
