Consider the perceptron with 6 input variables x1...6 and the corresponding weights w0 = -2, and wi = for i e{1,...,6}. Assume you are using the step function: if the weighted sum of the inputs is larger than zero, the output is 1. Otherwise, the output is zero. (a) What is the decision function of this perceptron. (b) Suppose the inputs are binary and take only 0 or 1. What does this perceptron implements? Explain. (c) How can you adapt the perceptron structure and weights to implement the same functionality in (b) but for n inputs? Explain.
