Is There a Threshold in Artificial Neural Nets?

artificial neural nets are modeled on the same kind of idea, except then instead of being actual nerve cells, there's just things in computer memory. So you end up with these big matrices or tensors, which say, I've got this whole vector of values,. And I'm going to determine from that a new sequence of values. The way it works is in an artificial neural net, and probably in an actual neural net in our brains, there are this succession of layers.
