Overview

From Wikipedia, the free encyclopedia · Read full article · Text CC BY-SA 4.0

In information theory, an entropy coding is any lossless data compression method that attempts to approach the lower bound declared by Shannon's source coding theorem, which states that any lossless data compression method must have an expected code length greater than or equal to the entropy of the source.
