Abstract
In one embodiment, the present invention provides a method comprising propagating a first set and a second set of axonal firing events through a symmetric core circuit in a first direction and a second direction, respectively. The symmetric core circuit comprises a first core module and a second core module, and each core module comprises an interconnection network for interconnecting multiple electronic neurons with multiple electronic axons. The method further comprises, for at least one neuron, receiving an axonal firing event via an interconnected axon, and, for at least one neuron, generating a neuronal firing event according to a neuronal activation function. Each core module of the symmetric core circuit has a corresponding adaptive lookup table, the corresponding adaptive lookup table used to determine target axons for neuronal firing events generated by neurons in the core module.
