Leveraging Hierarchical Representationsfor Preserving Privacy and Utility in Text
TABLE III: Correct author predictions (lower is better)
['[ITALIC] ε', 'Pan-11 small', 'Pan-11 large', 'Pan-12 set-A', 'Pan-12 set-C', 'Pan-12 set-D', 'Pan-12 set-I']
It also extends guarantees to authors with thousands of words. As ε increases, the privacy guarantees decrease as clearly evidenced by the PAN11 tasks. We only show results for Kopell’s algorithm because other evaluations perform worse on the baselines. e.g. PAN18 identifies only 65 and 50 authors, while PAN19-SVM identifies 54 and 35 authors in the PAN11 small and large datasets.
