Figure 11.

The evaluation results of DP ML tools on data utility for different data sizes (Table 2) and $ϵ$ values (Table 3). RMSPE is defined in Section 2.1. The sub-plots (a–c) present the results on Health Survey with data size 8000, 9000, and 9358, respectively. The sub-plots (d–f) present the results on Parkinson with data size 4000, 5000, and 5499, respectively. The sub-plots (g–i) repeat the results in (d), (e), and (f), respectively, with a larger y-axis scale.
