The Multistate Anti-Terrorism Information Exchange Program, also known by the acronym MATRIX, was a U.S. federally funded data mining system originally developed for the Florida Department of Law Enforcement described as a tool to identify terrorist subjects. The system was reported to analyze government and commercial databases to find ...
The Employees' Social Security Act 1969 ( Malay: Akta Keselamatan Sosial Pekerja 1969 ), is a Malaysian laws which enacted to provide social security in certain contingencies and to make provision for certain other matters in relation to it. The law is enforced by the Social Security Organization or PERKESO .
In mathematics, Choi's theorem on completely positive maps is a result that classifies completely positive maps between finite-dimensional (matrix) C*-algebras. An infinite-dimensional algebraic generalization of Choi's theorem is known as Belavkin 's "Radon–Nikodym" theorem for completely positive maps.
In statistics, the projection matrix , [1] sometimes also called the influence matrix [2] or hat matrix , maps the vector of response values (dependent variable values) to the vector of fitted values (or predicted values). It describes the influence each response value has on each fitted value. [3] [4] The diagonal elements of the projection ...
In mathematics, a stochastic matrix is a square matrix used to describe the transitions of a Markov chain. Each of its entries is a nonnegative real number representing a probability. [1] [2] : 9–11 It is also called a probability matrix, transition matrix, substitution matrix, or Markov matrix. [2] : 9–11 The stochastic matrix was first ...
Definition. The adjugate of A is the transpose of the cofactor matrix C of A , In more detail, suppose R is a unital commutative ring and A is an n × n matrix with entries from R. The (i, j) - minor of A, denoted Mij, is the determinant of the (n − 1) × (n − 1) matrix that results from deleting row i and column j of A.
The Matrix is an American cyberpunk [1] media franchise consisting of four feature films, beginning with The Matrix (1999) and continuing with three sequels, The Matrix Reloaded, The Matrix Revolutions (both 2003), and The Matrix Resurrections (2021). The first three films were written and directed by the Wachowskis and produced by Joel Silver.
Gram matrix. In linear algebra, the Gram matrix (or Gramian matrix, Gramian) of a set of vectors in an inner product space is the Hermitian matrix of inner products, whose entries are given by the inner product . [1] If the vectors are the columns of matrix then the Gram matrix is in the general case that the vector coordinates are complex ...
