Abstract
Embodiments are described for determining and/or estimating a nearest neighbor to a data vector in a dataset are presented. Some embodiments redistribute data vectors between clusters based upon the character of the clusters to more evenly balance the computational load. Some embodiments employ Locality Sensitive Hashing (LSH) functions as part of the clustering and remove redundant data vectors from the data set to mitigate unbalanced computation. The disclosed embodiments may facilitate the analysis of very large and/or very high dimensional datasets with reasonable runtimes.
