Detecting abrupt changes in random fields
ESAIM: Probability and Statistics, Volume 6 (2002), pp. 189-209.

This paper is devoted to the study of some asymptotic properties of a M-estimator in a framework of detection of abrupt changes in random field’s distribution. This class of problems includes e.g. recovery of sets. It involves various techniques, including M-estimation method, concentration inequalities, maximal inequalities for dependent random variables and φ-mixing. Penalization of the criterion function when the size of the true model is unknown is performed. All the results apply under mild, discussed assumptions. Simple examples are provided.
