(a) Sketch a diagram of a perceptron with three inputs x1, x2, x3 and weights w1, w2, w3. Label the inputs, weights, and output.

(b) Write the expression for the output in terms of the inputs and the weights, assuming a threshold of 0.

(c) What is the output when the inputs are −3, 2, 1 and the weights are 0, 0.2,

−0.2?

(d) What is the output if w1 is increased to 0.1, but everything else is kept the same?
