1. Determine the class of y [1.22] using the 1-NN classifier and the 3-NN classifier, both using the training examples from Table 3.7. Explain why the two 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. . Table 3.7 A simple set of training examples for the exercises 1 1 1 2 3 3 3 4 5 1 2 4 3 0 2 5 4 3 class + + + +
