“…Our protocol, specifically the SampleNoise procedure (Algorithm 4), will select the following parameters: µ υ = 65, µ η = 132, µ κ = 459, µ λ = 680, µ χ = 699. Plugging this back into (7) implies that the expected total number of noise registers added is ≤ 18K, which is an acceptable overhead for, e.g., sketch size m = 100K. Note that the number of noise registers can be reduced further by allocating more privacy budget to χ , κ , λ , but will result in worse accuracy (as indicated by ( 9), ( 8)).…”
