Cover Tree Search
Cover Tree Search Cover tree search is a metric space search structure designed for nearest neighbor queries. It builds a hierarchy of points where each level covers the level below with exponentially shrinking distance bounds. It provides strong theoretical guarantees in spaces with bounded intrinsic dimension. Problem Given a set of points $S$ in a metric space and a query point $q$, find: $$ \arg\min_{p \in S} d(p, q) $$...
