The Adaptive mechanism is the most reliable and best performing mechanism, in terms of overall data utility, with minimal tuning across most cases. -Skip performs optimally in data sets with a lower value range where approximation fits best. -The {\thething} selection component introduces a reasonable data utility decline to all of our mechanisms however, the Adaptive handles it well and bounds the data utility to higher levels compared to user-level protection. +Skip performs optimally in data sets with a smaller target value range, where approximation fits best. +The {\thething} selection component introduces a reasonable data utility decline to all of our mechanisms however, the Adaptive handles it well and bounds the data utility to higher levels compared to user-level protection.\kat{it would be nice to see it clearly on Figure 5.5. (eg, by including another bar that shows adaptive without landmark selection)} In terms of temporal correlation, we observe that under moderate and strong temporal correlation, a greater average regular--{\thething} event distance in a {\thething} distribution causes greater overall privacy loss. +Finally, the contribution of the {\thething} privacy on enhancing the data quality, while preserving $\epsilon$-differential privacy is demonstrated by the fact that the selected, Adaptive mechanism provides better data quality than the user-level mechanism.
