WebApr 11, 2024 · The nearest neighbor graph (NNG) analysis is a widely used data clustering method [ 1 ]. A NNG is a directed graph defined for a set E of points in metric space. Each point of this set is a vertex of the graph. The directed edge from point A to point B is drawn for point B of the set whose distance from point A is minimal.
