A new adaptive local polynomial density estimation procedure on complicated domains
Karine Bertin, Nicolas Klutchnikoff, Frédéric Ouimet
This paper presents a novel approach for pointwise estimation of multivariate density functions on known domains of arbitrary dimensions using nonparametric local polynomial estima…
Learning the regularity of multivariate functional data
Omar Kassi, Nicolas Klutchnikoff, Valentin Patilea
Combining information both within and between sample realizations, we propose a simple estimator for the local regularity of surfaces in the functional data framework. The independ…
Adaptive functional principal components analysis
Sunny G. W. Wang, Valentin Patilea, Nicolas Klutchnikoff
Functional data analysis almost always involves smoothing discrete observations into curves, because they are never observed in continuous time and rarely without error. Although s…
