A Locality Sensitive Hashing Technique for Categorical Data
Kyung Mi Lee, Keon Myung Lee · Applied Mechanics and Materials · 2012
The measured data may contain various types of attributes such as continuous, categorical, and set-valued attributes. Several locality-sensitive hashing techniques, which enable to find similar pairs of data in a fast and approximate way, have been developed for data with either numeric or set-valued attributes. This paper introduces a new locality sensitive-hashing technique applicable to data with categorical attributes.
