LO 2.2.2.A

Learning Objective: Calculate the output of a perceptron neuron.

Review:

• A perceptron takes several binary inputs, x1,x2,...xn , and produces a single binary output

• Each input xi is assigned a weight wi, a real number expressing the “relevance” of the specific xi.

• The neuron's output, 0 or 1, is determined by whether the weighted sum

 ∑wj xj is less than or greater than some threshold value.

• A threshold is a  real number  parameter of the neuron
