Thanks BrainShit from the other forum. (Name is correct, LOL)

Papers like below are very important to validate Akida technology in various use cases.

Some small snippets:

Particular emphasis is placed on models based on temporalcoding, where crucial information is encoded in the timing of neuron spikes. These models promise evengreater efficiency of resulting networks, as they maximize the sparsity properties inherent in SNN. Areliable metric capable of comparing different architectures in a hardware-agnostic way is developed toestablish a clear theoretical dependence between architecture parameters and the energy consumption thatcan be expected onboard the spacecraft. The potential of this novel method and his flexibility to describespecific hardware platforms is demonstrated by its application to predicting the energy consumption of aBrainChip Akida AKD1000 neuromorphic processor.

A preliminary successfuldemonstration is given for the BrainChip Akida AKD1000 neuromorphic processor. Benchmark SNNmodels, both latency and rate based, exhibited a minimal loss in accuracy, compared with their equivalentANN, with significantly lower (from −50 % to −80 %) EMAC per inference. An even greater energyreduction can be expected with SNN implemented on actual neuromorphic devices, with respect tostandard ANN running on traditional hardware.
