MULTI-SCALE SPATIO-TEMPORAL NEURAL NETWORK SYSTEM

摘要

Embodiments of the invention relate to a multi-scale spatio-temporal neural network system. One embodiment comprises a neural network including multiple heterogeneous neuron populations that operate at different time scales. Each neuron population comprises at least one digital neuron. Each neuron population further comprises a time scale generation circuit that controls timing for operation of said neuron population, wherein each neuron of said neuron population integrates neuronal firing events at a time scale corresponding to said neuron population. The neural network further comprises a plurality of synapses interconnecting the neurons, wherein each synapse interconnects a neuron with another neuron. At least one neuron receives neuronal firing events from an interconnected neuron that operates at a different time scale.

1. A neural network, comprising:
a processor; multiple heterogeneous neuron populations that operate at different time scales, wherein each neuron population comprises:
at least one digital neuron; anda time scale generation circuit that controls timing for operation of each neuron of said neuron population by:
counting the number of clock steps generated by a clock; andgenerating a time step upon determining that the number of clock steps reaches a time scale threshold parameter of said neuron population, wherein the time step generated triggers each neuron of said neuron population to integrate neuronal firing events at a time scale corresponding to said neuron population; and a plurality of synapses interconnecting the neurons, wherein each synapse interconnects a neuron with another neuron, and wherein at least one neuron receives neuronal firing events from an interconnected neuron that operates at a different time scale.
