Nonparametric statistical inference for the context tree of a stationary ergodic process
Sandro Gallo, Florencia Leonardi
We consider the problem of estimating the context tree of a stationary ergodic process with finite alphabet without imposing additional conditions on the process. As a starting poi…
Characterization of the stability of chains associated with -measures
Christophe Gallesco, Sandro Gallo, Daniel Yasumasa Takahashi
In this paper we introduce a notion of asymptotic stability of a probability kernel, which we call dynamic uniqueness. We say that a kernel exhibits dynamic uniqueness if all the s…
Continuity properties of a factor of Markov chains
Walter A. F. de Carvalho, Sandro Gallo, Nancy L. Garcia
Starting from a Markov chain with a finite alphabet, we consider the chain obtained when all but one symbol are undistinguishable for the practitioner. We study necessary and suffi…
Rumor processes on and discrete renewal processes
Sandro Gallo, Nancy L. Garcia, Valdivino Vargas Junior +1
We study two rumor processes on , the dynamics of which are related to an SI epidemic model with long range transmission. Both models start with one spreader at site and ig…
