Earth Mover's Distance: Data-Dependent Locality Sensitive Hashing
Data-dependent LSH improves EMD approximation by a quadratic factor.
New Data-Dependent LSH for Earth Mover's Distance
The author presents a new data-dependent LSH scheme for the Earth Mover's Distance, significantly improving nearest neighbor search approximations. By leveraging data-dependent techniques, the approach achieves a ˜O(log s) approximation.
