EFANNA : An Extremely Fast Approximate Nearest Neighbor Search Algorithm Based on kNN Graph

23 Sep 2016 Cong Fu Deng Cai

Approximate nearest neighbor (ANN) search is a fundamental problem in many areas of data mining, machine learning and computer vision. The performance of traditional hierarchical structure (tree) based methods decreases as the dimensionality of data grows, while hashing based methods usually lack efficiency in practice...
