Query: Towards Instance-Optimal Private Query Release   We study efficient mechanisms for the query release problem in differential
privacy: given a workload of $m$ statistical queries, output approximate
answers to the queries while satisfying the constraints of differential
privacy. In particular, we are interested in mechanisms that optimally adapt to
the given workload. Building on the projection mechanism of Nikolov, Talwar,
and Zhang, and using the ideas behind Dudley's chaining inequality, we propose
new efficient algorithms for the query release problem, and prove that they
achieve optimal sample complexity for the given workload (up to constant
factors, in certain parameter regimes) with respect to the class of mechanisms
that satisfy concentrated differential privacy. We also give variants of our
algorithms that satisfy local differential privacy, and prove that they also
achieve optimal sample complexity among all local sequentially interactive
private mechanisms.
