Informational Divergence Approximations to Product Distributions
Abstract
The minimum rate needed to accurately approximate a product distribution based on an unnormalized informational divergence is shown to be a mutual information. This result subsumes results of Wyner on common information and Han-Verd\'u on resolvability. The result also extends to cases where the source distribution is unknown but the entropy is known.
