Carlos Antonio Pinzón, Ehab ElSalamouny, Lucas Massot +3
Randomized Response (RR) is a protocol designed to collect and analyze categorical data with local differential privacy guarantees. It has been used as a building block of mechanis…
Uniform Distributions on p-Balls and the Singular Role of in p-Norm Geometry
Carlos Pinzón
This paper studies the relationship between volume and surface uniform measures on n-dimensional p-balls under the p-norm. It is proved that for p=1, p=2 and p=infinity, and only f…
Jeffrey's update rule as a minimizer of Kullback-Leibler divergence
Carlos Pinzón, Catuscia Palamidessi
In this paper, we show a more concise and high level proof than the original one, derived by researcher Bart Jacobs, for the following theorem: in the context of Bayesian update ru…
