Abstract
Presented herein are embodiments of a fast search on graph methodology for Maximum Inner Product Search (MIPS). This optimization problem is challenging since traditional Approximate Nearest Neighbor (ANN) search methods may not perform efficiently in the nonmetric similarity measure. Embodiments herein are based on the property that a Möbius/Möbius-like transformation introduces an isomorphism between a subgraph of-Delaunay graph and Delaunay graph for inner product. Under this observation, embodiments of a novel graph indexing and searching methodology are presented to find the optimal solution with the largest inner product with the query. Experiments show significant improvements compared to existing methods.
