Proposes a novel connection between kernel density estimation and sparse similarity graph construction
Algorithm runs in near-linear time when dimensionality is constant
Outperforms competing methods on runtime while achieving comparable accuracy
Enables scaling to larger datasets than prior approaches
Fast similarity graph construction
This paper presents a new algorithm to efficiently construct a sparse similarity graph from a dataset that approximates the fully connected graph. The key idea is reducing similarity graph construction to kernel density estimation. Experiments show the algorithm is much faster and scales to larger datasets than prior methods.
