along similar lines, there’s a popular demonstration of an opamp used as a simple neuron to make a photocell track the sun.
I don’t know why people keep leaving out the “artificial” part in artificial neural networks. They’re so far removed from real neural networks that the confusion would be funny if it wasn’t a mark of naivety and hubris.
I think it’s implied nowadays; if you say “neural network”, that’s understood to mean the machine learning model, not to imply any kind of claim about brains. People who work on accurate simulations of brains tend to use other terms like “neuronal modeling”.
This post offers very little over the original by Andrew Trask. But at least it was linked in the 1st paragraph.
