Random sample consensus (RANSAC) is an iterative method to estimate parameters of a mathematical model from a set of observed data that contains outliers...

In cryptography, a related-key attack is any form of cryptanalysis where the attacker can observe the operation of a cipher under several different keys...

In probability theory and statistics, a central moment is a moment of a probability distribution of a random variable about the random variable's mean;...

A compound Poisson process is a continuous-time stochastic process with jumps. The jumps arrive randomly according to a Poisson process and the size of...

In mathematics, a combinatorial explosion is the rapid growth of the complexity of a problem due to how the combinatorics of the problem is affected by...

In cryptography, the tabula recta (from Latin tabula rēcta) is a square table of alphabets, each row of which is made by shifting the previous one to the...

In statistics, data transformation is the application of a deterministic mathematical function to each point in a data set—that is, each data point zi...

In classical cryptography, the bifid cipher is a cipher which combines the Polybius square with transposition, and uses fractionation to achieve diffusion...

In mathematics, a magic cube is the 3-dimensional equivalent of a magic square, that is, a collection of integers arranged in an n × n × n pattern such...

In control theory and signal processing, a linear, time-invariant system is said to be minimum-phase if the system and its inverse are causal and stable...

Ciphertext indistinguishability is a property of many encryption schemes. Intuitively, if a cryptosystem possesses the property of indistinguishability...

In mathematics, particularly in linear algebra, a flag is an increasing sequence of subspaces of a finite-dimensional vector space V. Here "increasing"...

In mathematical logic, a first-order language of the real numbers is the set of all well-formed sentences of first-order logic that involve universal and...

In geometry, the truncated triakis tetrahedron, or more precisely an order-6 truncated triakis tetrahedron, is a convex polyhedron with 16 faces: 4 sets...

In decision analysis, the clarity test (or clairvoyant test) is a test of how well a model element is defined. Although nothing (outside a formal system)...

Given a unital C*-algebra A {\displaystyle {\mathcal {A}}} , a *-closed subspace S containing 1 is called an operator system. One can associate to each...

In mathematics, the term weak inverse is used with several meanings. In the theory of semigroups, a weak inverse of an element x in a semigroup (S, •)...

The Institute for Structural Research (Instytut Badań Strukturalnych or IBS) is an independent scientific foundation based in Warsaw, established in 2006...

Cepstral mean and variance normalization (CMVN) is a computationally efficient normalization technique for robust speech recognition. The performance of...
