SPIKE TAGGING FOR DEBUGGING, QUERYING, AND CAUSAL ANALYSIS

Embodiments of the invention relate to spike tagging for a neural network. One embodiment comprises a neural network including multiple electronic neurons and a plurality of weighted synaptic connections interconnecting the neurons. An originating neuron of the neural network generates a spike event and a message tag that includes information relating to said originating neuron. A neuron of the neural network receives a spike event and a message tag from an interconnected neuron. In response to one or more received spike events, a receiving neuron spikes and sends a message tag selected from received message tags to an interconnected neuron.
