Abstract
Do stochastic algorithms fall into traps? We are considering the valid ity of commonly held claims: ''a stochastic gradient algorithm only co nverges towards one of the local minima'' or ''a stochastic algorithm only converges towards an asymptotically stable solution of the associ ated differential equation''. We prove that a stochastic algorithm doe s not fall into a regular trap if the noise is exciting in a repulsive direction.
