Redundancy in informationtheory is the number of bits used to transmit a message minus the number of bits of actual information in the message. Informally, it is the amount of wasted space used to transmit certain data. Data compression is a way to reduce or eliminate unwanted redundancy, while checksum s are a way of adding desired redundancy for purposes of error detection when communicating over a noisy channel of limited channel capacity capacity . Quantitative definition In describing the redundancy of raw data, recall that the Entropy rate rate of a source of information is the average Information entropy entropy per symbol. For memoryless sources, this is merely the entropy of each symbol, while, in the most general case of a stochastic process, it is math r lim n to infty frac 1 n H M 1, M 2, dots M n , math the limit, as n goes to infinity, of the joint entropy of the first n symbols divided by n . It is common in informationtheory to speak of the rate or Information entropy entropy of a language. This is appropriate, for example, when the source of information is English prose. The rate of a memory less source is simply math H M math , since by definition there is no interdependence of the successive messages of a memory less source. The absolute rate of a language or source ... Aspects, p. 248 262, Springer 2010.

A Z channel is a communications channel used in coding theory and informationtheory to model the behaviour of some data storage systems. Definition A Z channel or a binary asymmetric channel is a channel with binary input and binary output where the crossover 1 0 occurs with nonnegative probability p whereas the crossover 0 1 never occurs. In other words, if X and Y are the random variable s describing the probability distributions of the input and the output of the channel, respectively, then the crossovers of the channel are characterized by the conditional probability conditional probabilities Prob Y 0 X 0 1 Prob Y 0 X 1 p Prob Y 1 X 0 0 Prob Y 1 X 1 1&minus p Capacity The channel capacity capacity math mathsf cap mathbb Z math of the Z channel math mathbb Z math with the crossover 1 0 probability p , when the input random variable X is distributed according to the geometric distribution with probability for the occurrence of 0, is calculated as follows. math mathsf cap mathbb Z math math max alpha mathsf H Y mathsf H Y mid X max p mathsf H Y sum x in 0,1 mathsf H Y mid X x mathsf Prob X x math math max alpha mathsf H 1 alpha 1 p mathsf H Y mid X 1 mathsf Prob X 1 math math max alpha mathsf H 1 alpha 1 p 1 alpha mathsf H p , math where math mathsf H cdot math is the binary entropy function .

An information diagram is a type of Venn diagram used in informationtheory to illustrate relationships among Shannon s basic Quantities of information measures of informationinformation entropy entropy , joint entropy , conditional entropy and mutual information . ref Fazlollah Reza. An Introduction to InformationTheory. New York McGraw Hill 1961. New York Dover 1994. ISBN 0 486 68210 2 ref ref R. W. Yeung, A First Course in InformationTheory. Norwell, MA New York Kluwer Plenum, 2002. ref An information diagram is a very useful pedagogical tool for teaching and learning about these basic measures of information, but using such a diagram carries some non trivial implications. For example, Shannon s entropy in the context of an information diagram must be taken as a signed measure . See the article Informationtheory and measure theory for more information. Random variables X, Y, and Z are said to form a Markov chain if Z and X are independent given Y. Thus, Y contains all the information of X that is relevant to Z. Thus, knowing X does not add anything to one s knowledge of Z when Y is given.
