What Is a Neuron? Trying 7 Kinds on 3 Tiny Puzzles
A neuron is a tiny calculator: it takes numbers in, adds them up with weights, and gives one number out. We try 7 kinds of neuron, from the simplest to a small group of neurons, on three tiny puzzles (AND, OR, XOR). The kind of neuron barely mattered. What mattered was having more than one neuron working together.
