DESCRIPTION:COLLOQUE DES SCIENCES MATHÉMATIQUES DU QUÉBEC\n\nTITLE: Estimat
 ing the mean of a random vector\n\nABSTRACT :\n	One of the most basic probl
 ems in statistics is the estimation of the mean of a random vector\, based
  on independent observations. This problem has received 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 perf
 ormance of mean estimators that allow heavy tails and adversarial contamin
 ation in the data. In particular\, we are interested in estimators that ha
 ve 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
 \nThis conference will be held in hybrid mode with a limited number of 21
