DPMechBernstein-class {diffpriv} | R Documentation |
A class that implements the Bernstein mechanism (not iterated version) of
differential privacy, for privatizing release of real-valued functions on
[0,1]^l
based on arbitrary datasets. Approximates the target
on a lattice.

list with slots per argument, actual privacy parameter and response:
mechanism response with length of target release:
privacyParams, sensitivity, latticeK, dims, target, response
.
scalar numeric norm of non-private target
on datasets.
The L_\infty
of the functions on a lattice.
show
: automatically prints the object.
releaseResponse
: releases Bernstein mechanism responses.
sensitivityNorm
: measures target
sensitivity.
sensitivity
non-negative scalar numeric maximum absolute target
sensitivity maximized over the lattice. Defaults to Inf
for use
with sensitivitySampler()
.
target
might be a closure that takes arbitrary dataset and returns a
real-valued function on [0,1]^l
.
gammaSensitivity
NA_real_
if inactive, or scalar in [0,1)
indicating that responses must be RDP with specific confidence.
latticeK
positive scalar integer-valued numeric specifying the lattice
resolution. Defaults to (invalid) NA_integer_
.
dims
positive scalar integer-valued numeric specifying the dimension
of released function domain. Defaults to (invalid) NA_integer_
.
