> Sigmoid Functions & Binary Classification

Sometimes you want to do binary classification.

This isn’t all there is.

They aren’t all set up like that. It’s a simplification of the effects of the limitations of the speed limits of synapses firing and vs the distances between them.

Spiking neural networks model the propagation more precisely, and have some promise. Their biggest issue is that it’s hard to get training data into an appropriate format for them… and that once you do... they don’t really seem to do better.
