We study the relationship between two characteristics of functional classes, pseudodimension and bracketing entropy. (Pseudodimension is a generalization of VC-dimension to classes of functions. Bracket entropy characterizes the $L_1$-error of one-sided approximation of a class by finite sets.) It is shown that classes of continuous functions with finite pseudodimension possess a finite bracketing $\varepsilon$-entropy for any $\varepsilon>0$. We establish a general result concerning the relationship between the VC-dimension of classes of sets and their bracketing entropy.
Keywords: bracketing entropy, measurable function, bracketing compactness of sets, random variable, probability space.
Mots-clés : pseudodimension, VC-dimension
