In information theory, redundancy measures the fractional difference between the entropy H(X) of an ensemble X, and its maximum possible value (| |). [1] [2] Informally, it is the amount of wasted "space" used to transmit certain data.
Concepts from information theory such as redundancy and code control have been used by semioticians such as Umberto Eco and Ferruccio Rossi-Landi to explain ideology as a form of message transmission whereby a dominant social class emits its message by using signs that exhibit a high degree of redundancy such that only one message is decoded ...
A variant of redundancy theory is the disquotational theory, which uses a modified form of Tarski's T-schema: To say that " 'P' is true" is to say that P. Yet another version of deflationism is the prosentential theory of truth, first developed by Dorothy Grover, Joseph Camp, and Nuel Belnap as an elaboration of
In probability theory and information theory, the mutual information (MI) of two random variables is a measure of the mutual dependence between the two variables. More specifically, it quantifies the " amount of information " (in units such as shannons ( bits ), nats or hartleys ) obtained about one random variable by observing the other random ...
In probability theory and in particular in information theory, total correlation (Watanabe 1960) is one of several generalizations of the mutual information. It is also known as the multivariate constraint (Garner 1962) or multiinformation (Studený & Vejnarová 1999). It quantifies the redundancy or dependency among a set of n random variables.
Redundancy (information theory), the number of bits used to transmit a message minus the number of bits of actual information in the message; Redundancy in total quality management, quality which exceeds the required quality level, creating unnecessarily high costs; The same task executed by several different methods in a user interface
Youth Services International confronted a potentially expensive situation. It was early 2004, only three months into the private prison company’s $9.5 million contract to run Thompson Academy, a juvenile prison in Florida, and already the facility had become a scene of documented violence and neglect.
In both lossy and lossless compression, information redundancy is reduced, using methods such as coding, quantization, DCT and linear prediction to reduce the amount of information used to represent the uncompressed data. Lossy audio compression algorithms provide higher compression and are used in numerous audio applications including Vorbis ...
