Differential Entropy   ::   AEP   ::   Discretization   ::   Other Entropy


Let $X_1,\ldots,X_n$\ be a sequence of random variables drawn

That is, it is the set for which the empirical differential entropy is close to the differential entropy.

For discrete random variables, we talked about the number of elements in the typical set. For continuous random variables, the analogous concept is the volume of the typical set.
