DESCRIPTION:Title: Estimating the mean of a random vector.\n\nAbstract: One
  of the most basic problems in statistics is the estimation of the mean of
  a random vector\, based on independent observations. This problem has rec
 eived renewed attention in the last few years\, both from statistical and 
 computational points of view. In this talk\, we review some recent results
  on the statistical performance of mean estimators that allow heavy tails 
 and adversarial contamination in the data. In particular\, we are interest
 ed in estimators that have a near-optimal error in all directions in which
  the variance of the one dimensional marginal of the random vector is not 
 too small. The material of this talk is based on a series of joint papers 
 with Shahar Mendelson.\n\nWeb site : http://crm.umontreal.ca/colloque-scie
