Machine Learning Speculation – Electric Circuit – If F.relu() is a Diode then what is the electric circuit equivalent of F.sigmoid() – Probability And Classification In An Electric Circuit?

Some morning idea I forgot to post from twitter.

Here is my machine learning physics electric circuit idea.

If F.relu() is a diode then what is the electric circuit equivalent of F.sigmoid()? Is there probability and classifications in an electric circuit also?

Then if moving a machine learning classification results could mimics some sort of gravity function? Since I suspect there two options. Either you move mass together or energy between them in a problem of potential.

So mass as a movable potential?
