1. Consider the following data set for pair (X, Y ) (0, 1),(2, 4),(4, 6),(7, 4),(10, 2) If we are using k-nearest neighbor learning what would be the predicted value for x = 5 if (a) k = 1. (b) k = 2 and we use no weighting function. (c) k = 2 and we use the weighting function wi = exp − (xi − x) 2 4
