Title : Survey sampling for non-parametric statistics and big-data

Abstract

In many situations, statisticians have at their disposal not only data but also weights arising from some survey sampling plan. Ignoring the method used to form the database can often result in a significant bias, thereby completely jeopardizing the estimation in non-parametric statistics. To avoid such drawbacks, variants of the estimators can be adopted, which incorporate the underlying sampling design through the use of the inclusion probabilities. The beginning of the Big Data era henceforth provides an additional motivation for investigating the impact of survey designs on statistical procedures. In contrast to naive sub-sampling, sampling designs with unequal probabilities offer a control over the efficiency of estimators. Use of appropriate sampling algorithms could appear as a natural alternative to distributed/parallelized strategies combined with fully random data splitting. In this course we will present

- some basic tools for studying Horvitz-Thompson type of empirical process. In particular we will show how the notion of negative association allows to obtain functional CLT for many sampling plans. 

- some applications of these ideas in several fields : how to efficiently estimate the tail of a r.v. when too many data are available and should be selected , how to perform gradient descent method in likelihood problem with too many observations.

We will conclude the course by some recent concentration results for some sampling designs and their extensions.

Title : Statistics for High-Dimensional Data

Abstract

We will discuss the topic of high-dimensional statistical inference, a theme which has attracted a lot of interest in statistics, machine learning and a wide range of data analysis problems in science and engineering. The presentations will cover methodology, algorithms, theory as well as applications (mainly) from genetics and genomics.
