A simple perceptron cannot represent XOR (or, generally, the parity function of its inputs). Describe what happens to the weights of a four-input, step-function perceptron, and beginning with all weights set to 0.1, as examples of the parity function arrive.
Answer to relevant QuestionsRecall from that there are 22n distinct Boolean functions of n inputs. How many of these are representable by a threshold perceptron?Suppose that a training set contains only a single example, repeated 100 times. In 80 of the 100 cases, the single output value is I; in the other 20, it is 0. What will a back- propagation network predict for this example, ...Adapt the vacuum world for reinforcement learning by including rewards for picking up each piece of dirt and for getting home and switching off. Make the world accessible by providing suitable percepts. Now experiment with ...Using DCG notation, write a grammar for a language that is just like Є1, except that it enforces agreement between the subject and verb of a sentence and thus does not generate “I smells the wumpus.”We forgot to mention that the text in Exercise 22.1 is entitled “Washing Clothes.” Reread the text and answer the questions in Exercise 22.7.
