Ergodic Randomized Algorithms and Dynamics over Networks
Chiara Ravazzi, Paolo Frasca, Roberto Tempo +1
Algorithms and dynamics over networks often involve randomization, and randomization may result in oscillating dynamics which fail to converge in a deterministic sense. In this pap…
Gossips and Prejudices: Ergodic Randomized Dynamics in Social Networks
Paolo Frasca, Chiara Ravazzi, Roberto Tempo +1
In this paper we study a novel model of opinion dynamics in social networks, which has two main features. First, agents asynchronously interact in pairs, and these pairs are chosen…
Almost sure convergence of a randomized algorithm for relative localization in sensor networks
Chiara Ravazzi, Paolo Frasca, Roberto Tempo +1
This paper regards the relative localization problem in sensor networks. We study a randomized algorithm, which is based on input-driven consensus dynamics and involves pairwise "g…
Distributed soft thresholding for sparse signal recovery
Chiara Ravazzi, Sophie M. Fosson, Enrico Magli
In this paper, we address the problem of distributed sparse recovery of signals acquired via compressed measurements in a sensor network. We propose a new class of distributed algo…
