Units of SynOps #108

Closed narduzzi closed 3 years ago

narduzzi commented 3 years ago

Hello,

I am wondering what the unit for synaptic operations is? When I simulate on a simple network, I get a matrix of shape (128, 15) as I simulate on 128 data samples during 15ms. I don't know how to interpret the values in this matrix:

print(simulation_data["synaptic_operations_b_t"][0])

// [0.00e+00 ... 6.20e-05 1.54e-04 1.54e-04 1.54e-04 2.66e-04 ... 6.32e-04 6.32e-04]

What is the meaning of synops? Why are synops smaller than 1?

Config
Python 3.7.9
SNNToolbox 0.6.0

Thanks for your help!

The synaptic operations are given in Million here (i.e. factor 1e6).

A synaptic operation happens when a spike is transmitted from a source neuron in one layer to a target neuron in the next layer.
