Exercise 3- Nearest Neighbors, We are given the following training examples: (1.2.3.2), (2.8, 8.5), (2,4.7), (0.9,2.9), (5.1,11) We want to apply a 3-nearest neighbor rule in order to perform regression. (a), Predict the label (real value) at each of the following two points: ₁ = 1.5 and x₂ = 4.5. (b)... - Instead of weighing the contribution of each of the 3 nearest neighbors equally, this time we want to perform distance-weighted nearest neighbor regression. What values do we predict now for x₁ = 1.5 and ₂ = 4.5?
