Observations on the Bias of Nonnegative Mechanisms for Differential Privacy
Aisling Mc Glinchey, Oliver Mason
We study two methods for differentially private analysis of bounded data and extend these to nonnegative queries. We first recall that for the Laplace mechanism, boundary inflated…
Bounding the l_2 sensitivity for positive linear observers
Aisling McGlinchey, Oliver Mason
We consider the design of differentially private Luenberger observers for positive linear systems. In particular, we derive a bound for the sensitivity of Luenberger observer…
Diagonal stability of a class of discrete-time positive switched systems with delay
Alexander Aleksandrov, Oliver Mason
A class of discrete-time nonlinear positive time-delay switched systems with sector-type nonlinearities is studied. Sufficient conditions for the existence of common and switched d…
Barabanov norms, Lipschitz continuity and monotonicity for the max algebraic joint spectral radius
Nicola Guglielmi, Oliver Mason, Fabian Wirth
We present several results describing the interplay between the max algebraic joint spectral radius (JSR) for compact sets of matrices and suitably defined matrix norms. In particu…
Diagonal Riccati Stability and the Hadamard Product
Alexander Aleksandrov, Oliver Mason, Anna Vorob'eva
We present an extension of a recent characterisation of diagonal Riccati stability and, using this, extend a result of Kraaijevanger on diagonal Lyapunov stability to Riccati stabi…
Optimal Differentially Private Mechanisms for Randomised Response
Naoise Holohan, Douglas J. Leith, Oliver Mason
We examine a generalised Randomised Response (RR) technique in the context of differential privacy and examine the optimality of such mechanisms. Strict and relaxed differential pr…
