USER IDENTIFICATION THROUGH SUBSPACE CLUSTERING
First Claim
1. A method to detect a number of individual users corresponding to movie ratings in a composite set of movie ratings, the method comprising:
- accessing the composite set of movie ratings by loading the composite set into a rating analysis engine;
accessing a set of movie profiles by loading the set of movie profiles into the rating analysis engine;
determining a number of partitions of movie ratings present in the composite set by processing the composite set using the movie profiles, wherein the number of partitions is determined iteratively using subspace clustering of ratings from the composite set;
outputting the number of determined partitions, the determined number of partitions corresponding to the number of individual users.

Abstract
A method to detect a number of individual users included in a composite set of movie ratings having ratings from a plurality of individual users includes accessing the composite set of movie ratings and movie profiles and loading the composite set and movie profiles into a rating analysis engine. Processing the composite set along with the movie profiles determines a number of partitions present in the composite set, wherein the number of partitions is determined iteratively using subspace clustering of ratings from the composite set. The determined number of partitions is output and corresponds to the number of individual users included in the composite set of movie ratings.
