Universal Coding can refer to one of two concepts in data compression:
- Universal code (data compression), a fixed prefix code that, for any probability mass function, has a data compression ratio within a constant of the optimal prefix code
- Universal source coding, a data compression method that asymptotically approaches the data compression ratio of the optimal data compression method, e.g., LZ77 and LZ78
Famous quotes containing the word universal:
“Poets ... are the only people to whom love is not only a crucial, but an indispensable experience, which entitles them to mistake it for a universal one.”
—Hannah Arendt (1906–1975)
