1. Determine the class of y classifier, both using the training examples from Table 3.7. Explain why the two [1, 22] using the 1-NN classifier and the 3-NN classifiers differ in their classification behavior. 2. Use the examples from Table 3.7 to classify object y = [3, 3] with the 5- NN classifier. Note that two nearest neighbors are positive and three nearest neighbors are negative. Will weighted 5-NN classifier change anything? To see what is going on, plot the locations of the examples in a graph.
