SUMMARY: (...): F. Angeletti (ENS Lyon): Critical order for moment estimati
 on : insights from statistical physics.
DESCRIPTION:: Critical order for moment estimation : insights from statisti
 cal physics.\nBy Florian Angeletti ENS Lyon\n\nAbstract:\nMoment estimatio
 n is one of the most basic question in statistical signal processing.\nFor
  i.i.d. random variables and a infinite number of observations\\\, the law
  of large numbers implies that the classical moment estimator converges to
 wards the theoretical moment. However\\\, these hypothesis are not really 
 satisfied in practical settings where only a finite number of observations
  is available and most data are correlated.\nIt is therefore quite natural
  to ask ourselves: up to which order can moments be reliably estimated fro
 m a given number of observation? In this presentation\\\, I will show how 
 the notion of glassy phase transition developed for studying disordered sy
 stems in statistical physics can help to answer such a question.
