SUMMARY:Stochastic Analysis Seminar – Laurent Miclo (CNRS)
DESCRIPTION:Laurent Miclo\nTitle: On fraudulent stochastic algorithms\nAbst
 ract\n\n\n\nWe introduce and analyse the almost sure convergence of a stoc
 hastic algorithm for the global minimisation of smooth functions.\nThis di
 ffusion process is called fraudulent because it requires the knowledge of 
 minimal value of the function. Nevertheless\, its investigation is not wit
 hout interest\, since in particular it appears as the limit behaviour of n
 on-fraudulent and time-inhomogeneous swarm mean-field algorithms for globa
 l optimisation or in stochastic gradient descent algorithms in over-parame
 trised deep learning applications. The talk is based on collaborations wit
 h Benaïm\, Bolte and Villeneuve.\n\n\n
