We addressed an efficient algorithm for approximate nearest neighbor search in high dimensional $L_p$ space. Efficient computation of the search is important since the computational complexity of approximate nearest neighbor search grows as the size of dataset increases. We introduced an index called randomized neighbor search table and derived an algorithm that utilizes hyperspheres. Our simulation result shows that the algorithm achieved good performance both in terms of spacial and time complexity. In addition, we worked on an issue on distributed processing of the search towards a scalable approximate nearest search. |
