Warren S. McCulloch & Walter H. Pitts Neuron model

This is a very simple model for a neuron. Let's say there are N number of inputs. The neuron will only fire when the sum of all the input is greater than a threshold.

• x1 + x2 ....... + xn > t => y=1 let say t is the threshold
• x1 + x2 ....... + xn < t => y=0

Perceptron Model

In this model each input has been assigned weight. If w1x1+w2x2+ ...... wnxn > threshold then y=1 else y=0
