Hierarchical Satellite System Graph for Approximate Nearest Neighbor Search on Big Data
We propose Hierarchical Satellite System Graph (HSSG) and present its index algorithm and search algorithm. The index process can be distributed deployed due to the good parallelism of our designed hierarchical structure. The theoretical analysis reveals that HSSG decreases the search steps and reduces the computational cost and reduces the search time by searching on the hierarchical structure.
