Claim 12:
13. The method of claim 2, wherein clustering the first sensitive data instance and the second sensitive data instance into the first cluster based on similarities between the first image representation and the second image representation further comprises:
generating a similarity matrix, wherein a corresponding element of the similarity matrix represents similarity between a corresponding first test image representation and a corresponding second test image representation, and wherein the first set of image representations comprises the corresponding first test image representation and the corresponding second test image representation;
updating a responsibility matrix iteratively, wherein a corresponding element of the responsibility matrix represents responsibility of the corresponding first test image representation to exhibit the corresponding second test image representation as a corresponding exemplar;
updating an availability matrix iteratively, wherein a corresponding element of the availability matrix represents availability of the corresponding first test image representation to act as an exemplar to the corresponding second test image representation; and
based on the responsibility matrix and the availability matrix, generating a set of assignments, wherein each assignment of the set of assignments links an associated image representation of the first set of image representations with a corresponding exemplar image representation of the first set of image representations.
