Minimal Effort to Consensus (MEC) polarization measure
Jesús Aranda, Juan Francisco Díaz, Juan Camilo Narváez +4
We introduce the Minimum Effort to Consensus (MEC), a measure that quantifies polarization as resistance to consensus: a population is highly polarized when much effort is needed t…
Estimating the True Distribution of Data Collected with Randomized Response
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…
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…
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…
Causal Discovery Under Local Privacy
Rūta Binkytė, Carlos Pinzón, Szilvia Lestyán +3
Differential privacy is a widely adopted framework designed to safeguard the sensitive information of data providers within a data set. It is based on the application of controlled…
Counting and Computing Join-Endomorphisms in Lattices (Revisited)
Carlos Pinzón, Santiago Quintero, Sergio Ramírez +2
Structures involving a lattice and join-endomorphisms on it are ubiquitous in computer science. We study the cardinality of the set of all join-endomorphisms of a…
On the Computation of Distributed Knowledge as the Greatest Lower Bound of Knowledge
Santiago Quintero, Carlos Pinzón, Sergio Ramírez +1
Let be a finite lattice and be the set of join endomorphisms of . We consider the problem of given and , finding the greatest lo…
Frequency Estimation of Evolving Data Under Local Differential Privacy
Héber H. Arcolezi, Carlos Pinzón, Catuscia Palamidessi +1
Collecting and analyzing evolving longitudinal data has become a common practice. One possible approach to protect the users' privacy in this context is to use local differential p…
Minimizing Information Leakage under Padding Constraints
Sebastian Simon, Cezara Petrui, Carlos Pinzón +1
An attacker can gain information of a user by analyzing its network traffic. The size of transferred data leaks information about the file being transferred or the service being us…
Causal Discovery for Fairness
Rūta Binkytė-Sadauskienė, Karima Makhlouf, Carlos Pinzón +2
It is crucial to consider the social and ethical consequences of AI and ML based decisions for the safe and acceptable use of these emerging technologies. Fairness, in particular,…
On the impossibility of non-trivial accuracy under fairness constraints
Carlos Pinzón, Catuscia Palamidessi, Pablo Piantanida +1
One of the main concerns about fairness in machine learning (ML) is that, in order to achieve it, one may have to trade off some accuracy. To overcome this issue, Hardt et al. prop…
