Entropy (information theory) — In information theory, entropy is a measure of the uncertainty associated with a random variable. The term by itself in this context usually refers to the Shannon entropy, which quantifies, in the sense of an expected value, the information… … Wikipedia
Entropy (computing) — In computing, entropy is the randomness collected by an operating system or application for use in cryptography or other uses that require random data. This randomness is often collected from hardware sources, either pre existing ones such as… … Wikipedia
Entropy — This article is about entropy in thermodynamics. For entropy in information theory, see Entropy (information theory). For a comparison of entropy in information theory with entropy in thermodynamics, see Entropy in thermodynamics and information… … Wikipedia
Entropy rate — The entropy rate of a stochastic process is, informally, the time density of the average information in a stochastic process. For stochastic processes with a countable index, the entropy rate H(X) is the limit of the joint entropy of n members of … Wikipedia
Entropy encoding — In information theory an entropy encoding is a lossless data compression scheme that is independent of the specific characteristics of the medium. One of the main types of entropy coding creates and assigns a unique prefix free code to each… … Wikipedia

Entropy — A mathematical measurement of the degree of uncertainty of a random variable. Entropy in this sense is essentially a measure of randomness. It is typically used by financial analysts and market technicians to determine the chances of a specific… … Investment dictionary
entropy — [19] The term entropy was coined (as entropie) in 1865 by the German physicist Rudolph Clausius (1822–88), formulator of the second law of thermodynamics. It was he who developed the concept of entropy (a measure of the disorder of a system at… … The Hutchinson dictionary of word origins
