1.6.4.1. Brute Force¶. Fast computation of nearest neighbors is an active area of research in machine learning. The most naive neighbor search implementation involves the brute-force computation of distances between all pairs of points in the dataset: for \(N\) samples in \(D\) dimensions, this approach scales as \(O[D N^2]\).
