Cоnsider the fоllоwing dаtа points аnd their class labels: [P1: (2, 3, 4), A], [P2: (8, 3, 4), B], [P3: (8, 4, 1), B], [P4: (6, 4, 1), A], [P5, (2, 3, 1), A]. We want to use the distance weighted 3-NN classification with this data. Each point at a distance of d has a vote of (1/d) for predicting thee class label. (a) (8) For the query point (5, 4, 4) find and report the data points in its 3-nearest-neighbor list, their weights for decision, and the class label that should be assigned to this query point. (b) (6) What is gained and what is lost when we increase the value of K in a K-NN classifier?
