Likelihood test in permutations with bias. Premier League and La Liga: surprises during the last 25 seasons
Giacomo Aletti
In this paper, we introduce the models of permutations with bias, which are random permutations of a set, biased by some preference values. We present a new parametric test, togeth…
A new nonlocal nonlinear diffusion equation for image denoising and data analysis
Giacomo Aletti, Monica Moroni, Giovanni Naldi
In this paper we introduce and study a new feature-preserving nonlinear anisotropic diffusion for denoising signals. The proposed partial differential equation is based on a novel…
A clustering algorithm for multivariate data streams with correlated components
Giacomo Aletti, Alessandra Micheletti
Common clustering algorithms require multiple scans of all the data to achieve convergence, and this is prohibitive when large databases, with data arriving in streams, must be pro…
Networks of reinforced stochastic processes: asymptotics for the empirical means
Giacomo Aletti, Irene Crimaldi, Andrea Ghiglietti
This work deals with systems of interacting reinforced stochastic processes, where each process is located at a vertex of a finite weighted direct graph, and…
