29. [ 2 points] In the figure below, there are 10 samples from a 1-dimensional dataset (i.e., 1 feature only, labeled p). Assume that all the samples belong to two classes only, namely " X " and "O". These samples are used to train a K-Nearest Neighbor classifier. In the case of ties, we prefer class " X ". Suppose we define the training error rate as the fraction of data points incorrectly classified. What is the training error rate of a 1-Nearest-Neighbor classifier trained on this data? (a) 0.3 (b) 1 (c) 0.1 (d) 0 (e) 0.5 Correct answers: (d) 30. [2 points] Referring to question 29, what is the training error rate of a 2-Nearest-Neighbor classifier trained on the same data? (a) 0.1 (b) 0.3 (c) 1 (d) 0.5 (e) 0 Correct answers: (b)
