Stochastics and Dynamics, 2020 A set [Formula: see text] is called predictive if for any zero entropy finite-valued stationary process [Formula: see text], [Formula: see text] is measurable with respect to [Formula: see text]. We know that [Formula: see text] is a predictive set. In this paper, we give sufficient conditions and necessary ones for a set to be predictive.
