FiRE - Finder of Rare Entities (FiRE)
The algorithm assigns rareness/ outlierness score to every
sample in voluminous datasets. The algorithm makes multiple
estimations of the proximity between a pair of samples, in
low-dimensional spaces. To compute proximity, FiRE uses
Sketching, a variant of locality sensitive hashing. For more
