DPrivBench - Mechanism Level: leaderboard

Metric: Accuracy (0-1, times 100) on the six mechanism tasks (mean of the per-task accuracies) of the DPrivBench Category 1 mechanism-level instances (a mechanism template instantiated with a concrete query function from a 49-function bank; positive instances calibrate the noise to the true sensitivity, paired negatives under-calibrate it); binary yes/no verdict on whether the stated differential privacy guarantee holds, five seeds, no tools; higher is better. Source: arxiv.org. Saturation forecast: Estimated already saturated. 11 models tracked.
