This package provides code to implement locality-sensitive hashing (LSH) in an optimum fashion. There are two pieces. A Python library that implements LSH and a Matlab routine that calculates the optimum parameters for LSH. The LSH implementation is based on a tutorial published by IEEE Malcolm Slaney, Michael Casey, "Locality-Sensitive Hashing for Finding Nearest Neighbors [Lecture Notes]," Signal Processing Magazine, IEEE , vol.25, no.2, pp.128-131, March 2008 doi: 10.1109/MSP.2007.914237 URL: http://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=4472264&isnumber=4472102 and also available at this URL http://www.slaney.org/malcolm/yahoo/Slaney2008-LSHTutorial.pdf The optimization algorithm is based on this article, which is currently under review.
