General oracle inequalities for a penalized log-likelihood criterion based on non-stationary data
Julien Aubert, Luc Lehéricy, Patricia Reynaud-Bouret
We prove oracle inequalities for a penalized log-likelihood criterion that hold even if the data are not independent and not stationary, based on a martingale approach. The assumpt…
