Details of the hypergraph:
Center hyperedge (induced by source paper "on the geometry of differential privacy"):
  Abstract: We consider the noise complexity of differentially private mechanisms in the setting where the user asks $d$ linear queries $f\colon\Rn\to\Re$ non-adaptively. Here, the database is represented by a vector in $\Rn$ and proximity between databases is measured in the $\ell_1$-metric. #R##N#We show that the noise complexity is determined by two geometric parameters associated with the set of queries. #R##N#We use this connection to give tight upper and lower bounds on the noise complexity for any $d \leq n$. We show that for $d$ random linear queries of sensitivity~1, it is necessary and sufficient to add $\ell_2$-error $\Theta(\min\{d\sqrt{d}/\epsilon,d\sqrt{\log (n/d)}/\epsilon\})$ to achieve $\epsilon$-differential privacy. Assuming the truth of a deep conjecture from convex geometry, known as the Hyperplane conjecture, we can extend our results to arbitrary linear queries giving nearly matching upper and lower bounds. #R##N#Our bound translates to error $O(\min\{d/\epsilon,\sqrt{d\log(n/d)}/\epsilon\})$ per answer. The best previous upper bound (Laplacian mechanism) gives a bound of $O(\min\{d/\eps,\sqrt{n}/\epsilon\})$ per answer, while the best known lower bound was $\Omega(\sqrt{d}/\epsilon)$. In contrast, our lower bound is strong enough to separate the concept of differential privacy from the notion of approximate differential privacy where an upper bound of $O(\sqrt{d}/\epsilon)$ can be achieved.
