We will train a Nearest Neighbor Regressor model on the following ten observations. All three variables x1, x2, and y are continuous variables. The label variable is y. The input features are x1 and x2. The distance measure is Chebyshev. The error is y minus the predicted y. The criterion is the sum of absolute error. Except for the trivial single neighbor solution, what is the number of neighbors that yields the smallest sum of absolute error? х1 x2 y 0.2 0.0 1.4 0.3 0.6 -1.0 0.4 0.0 1.8 0.5 0.2 1.8 0.5 0.6 0.4 0.5 0.6 0.4 0.5 0.8 1.2 0.7 0.0 2.4 0.7 0.4 1.0 0.8 0.6 2.0
