Binary entropy function — In information theory, the binary entropy function, denoted H(p) , or H {mathrm b}(p) ,, is defined as the entropy of a Bernoulli trial with probability of success p . Mathematically, the Bernoulli trial is modelled as a random variable X that… … Wikipedia
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
Binary symmetric channel — A binary symmetric channel (or BSC) is a common communications channel model used in coding theory and information theory. In this model, a transmitter wishes to send a bit (a zero or a one), and the receiver receives a bit. It is assumed that… … Wikipedia
Binary space partitioning — (BSP) is a method for recursively subdividing a space into convex sets by hyperplanes. This subdivision gives rise to a representation of the scene by means of a tree data structure known as a BSP tree.In simpler words, it is a method of breaking … 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 (ecology) — Ecological entropy is a measure of biodiversity in the study of biological ecology.DefinitionAssume that within a system of unlimited individuals, there exists n species of organisms (A 1, A 2, ..., A j, ..., A n), and the probability that an… … Wikipedia
Binary logarithm — NOTOC In mathematics, the binary logarithm (log2 n ) is the logarithm for base 2. It is the inverse function of n mapsto 2^n. The binary logarithm is often used in computer science and information theory (where it is frequently written lg n , or… … Wikipedia
Context-adaptive binary arithmetic coding — (CABAC) is a form of entropy coding used in H.264/MPEG 4 AVC video encoding. It is a lossless compression technique. It is notable for providing much better compression than most other encoding algorithms used in video encoding, and is one of the … Wikipedia
Truncated binary encoding — is an entropy encoding typically used for uniform probability distributions with a finite alphabet. It is parameterized by an alphabet with total size of number n . It is a slightly more general form of binary encoding when n is not a power of… … Wikipedia
