The Perceptron
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
State
A perceptron is a weighted sum with a starting balance and a yes-above-zero verdict — its knobs are all there is to it.
Show
No rules inside, no stored examples, no tree of questions: a row of knobs, and training will mean finding good settings.
Watch for
Set the knobs well and it sorts; badly and it babbles — everything rides on the settings.
