The work this thesis focuses on the choice of the smoothing parameter in the context of non-parametric estimation of the density function for stationary ergodic continuous time processes. The accuracy of the estimation depends greatly on the choice o

This dissertation introduces in its first part the field of signal processing on graphs. We start by reminding the required elements from linear algebra and spectral graph theory. Then, we define signal processing on graphs and give intuitions on its

Translation and Stationarity for Graph Signals

We propose a novel time shift like operator called the graph translation. We enforce that it is isometric and define it such that it shares with the time shift operator its key properties. Using the graph translation operator and its isometry, we pro

Some asymptotic properties for nonparametric estimation of functional of stationary continuous time processes

Autor: Didi, Sultana

Publikováno v: Statistiques [math.ST]. Université Pierre et Marie Curie-Paris VI, 2014. Français. ⟨NNT : 2014PA066191⟩

The work of this thesis focuses upon some nonparametric estimation problems. More precisely, considering kernel estimators of the density, the regression and the conditional mode functions associated to a stationary continuous-time process, we aim at
