NettetIn the above figure, x1 and x2 are inputs of the perceptron, and y is the result. w1 and w2 are weights of the edges x1-y and x2-y. Let us define a threshold limit 𝛳. If the value of y exceeds the threshold value, the output will be 1. Else the output will be 0. The equation is as follows. y ≤ 𝛳: output is 0.
