How is the output of a perceptron computed
WebPerceptron was introduced by Frank Rosenblatt in the late 1950's (Rosenblatt, 1958) with a learning algorithm on it. Perceptron may have continuous valued inputs. It works in the same way as the formal artificial neuron defined previously. Its activation is determined by equation: a=wTu + θ (6.1.1) Moreover, its output function is ... Web7 jan. 2024 · If the item to predict has values (-7.0, 3.0, 9.0) then the computed output is (0.20 * -7.0) + (-0.50 * 3.0) + (0.40 * 9.0) + 1.10 = -1.4 + (-1.5) + 3.6 + 1.1 = +1.8 and therefore the predicted class is +1. Of course the tricky part is determining the weights and bias values of a perceptron classifier. This is called training the model.
