There’s lots of good articles about perceptrons. To quickly summarise, a perceptron is essentially a method of separating a manifold with a hyperplane. This is just drawing a straight line to separate an n-dimensional space into two regions: True or False. I will interchangeably refer to these as neurons or perceptrons.
