Using the Distance Distribution for Approximate Similarity Queries in High-Dimensional Metric Spaces
15 years 11 months ago
We investigate the problem of approximate similarity (nearest neighbor) search in high-dimensional metric spaces, and describe how the distance distribution of the query object ca...
