Robust empirical mean Estimators
M. Lerasle, R. I. Oliveira
We study robust estimators of the mean of a probability measure , called robust empirical mean estimators. This elementary construction is then used to revisit a problem of aggr…
Oracle approach and slope heuristic in context tree estimation
A. Garivier, M. Lerasle
We introduce a general approach to prove oracle properties in context tree selection. The results derive from a concentration condition that is verified, for example, by mixing pro…
Markov Approximations of chains of infinite order in the -metric
Sandro Gallo, Matthieu Lerasle, Daniel Yasumasa Takahashi
We derive explicit upper bounds for the -distance between a chain of infinite order and its canonical -steps Markov approximation. Our proof is entirely constructive an…
Sharp oracle inequalities and slope heuristic for specification probabilities estimation in discrete random fields
Matthieu Lerasle, Daniel Y. Takahashi
We study the problem of estimating the one-point specification probabilities in non-necessary finite discrete random fields from partially observed independent samples. Our procedu…
