Measure of dependence between two variables
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.
Computer Science › Information theory
The generalized distributive law (GDL) is a generalization of the distributive property which gives rise to a general message passing algorithm.

Signal processing algorithm
The method of reassignment is a technique for sharpening a time-frequency representation (e.g. spectrogram or the short-time Fourier transform) by mapping the data to time-frequency coordinates that are nearer to the true region of support of the analyzed signal.
Computer Science › Information theory
A Z-channel is a communications channel model used in coding theory and information theory to represent certain data storage systems. In a Z-channel, 0 bits are always transmitted correctly, but 1 bits may be corrupted and received as 0s with some probability.

Probability distribution in quantum mechanics
A quantum t-design is a probability distribution over either pure quantum states or unitary operators which can duplicate properties of the probability distribution over the Haar measure for polynomials of degree t or less.

Digital audio format
MP3 (formally MPEG-1 Audio Layer III or MPEG-2 Audio Layer III) is an audio coding format developed largely by the Fraunhofer Society in Germany under the lead of Karlheinz Brandenburg.

Distortion of media caused by lossy data compression
In computing, a compression artifact (or artefact) is a noticeable distortion of digital media (including images, audio and video) caused by the application of lossy compression.

Number of digits needed to express a number in a particular base
In mathematics and computer science, optimal radix choice is the problem of choosing the base, or radix, that is best suited for representing numbers. Various proposals have been made to quantify the relative costs of using different radices in representing numbers, especially in computer systems.

Finds likely sequence of hidden states
The Viterbi algorithm is a dynamic programming algorithm that finds the most likely sequence of hidden events that would explain a sequence of observed events. The result of the algorithm is often called the Viterbi path. It is most commonly used with hidden Markov models (HMMs).
Computer Science › Information theory
Surprisal analysis is an information-theoretical analysis technique that integrates and applies principles of thermodynamics and maximal entropy. Surprisal analysis is capable of relating the underlying microscopic properties to the macroscopic bulk properties of a system.

Width and height of a display in pixels
The display resolution or display modes of a digital television, computer monitor, or other display device is the number of distinct pixels in each dimension that can be displayed.
Computer Science › Information theory
Type of linear code
In coding theory, a polynomial code is a type of linear code whose set of valid code words consists of those polynomials (usually of some fixed length) that are divisible by a given fixed polynomial (of shorter length, called the generator polynomial).
