We also see similar results with our generalization method in Figure 18.8c and d. While the
specic value of the utility that was dened for naïve Bayes does not exactly hold, we still see that
by performing generalization, we are able to decrease classication accuracy across multiple types
of classier.
18.6 EFFECT OF SANITIZATION ON UTILITY
Of course, if the data is to be used by a company, then there must still be some value in the post-
sanitization graph. To gauge the utility of the anonymized data set, in Table 18.7 we show the
results of various inference tests performed on nonsensitive deta
