Evaluator for knn algorithms, which expects two input columns, the exact neighbors and approximate neighbors.
Evaluator for knn algorithms, which expects two input columns, the exact neighbors and approximate neighbors. It compares
the results to determine the accuracy of the approximate results. Typically you will want to compute this over a
small sample given the cost of computing the exact results on a large index.
