In predictive analytics, a table of confusion (sometimes also called a confusion matrix) is a table with two rows and two columns that reports the number of true positives, false negatives, false positives, and true negatives. This allows more detailed analysis than simply observing the proportion of correct classifications (accuracy).
Matrix (protocol), an open standard for real-time communication. Matrix (record production), or master, a disc used in the production of phonograph records. Matrix number, of a gramophone record. Diode matrix, a two-dimensional grid of intersecting diodes. Display matrix, picture elements of an information display arranged as a matrix.
Phyllis and Aristotle, a fictional tale written in the 13th century, as depicted by artist Giovanni Buonconsiglio in the early 1500s. A dominatrix (/ ˌ d ɒ m ɪ ˈ n eɪ t r ɪ k s / DOM-in-AY-triks; pl. dominatrixes or dominatrices / ˌ d ɒ m ɪ ˈ n eɪ t r ɪ s iː z, ˌ d ɒ m ɪ n ə ˈ t r aɪ s iː z / DOM-in-AY-triss-eez, DOM-in-ə-TRY-seez), or domme, is a woman who takes the ...
Carol Myers-Scotton's Matrix Language-Frame (MLF) model is the dominant model of insertional code-switching. [37] The MLF model posits that there is a Matrix Language (ML) and an Embedded Language (EL). In this case, elements of the Embedded Language are inserted into the morphosyntactic frame of the Matrix Language.
A black carbon fibre (used as a reinforcement component) compared to a human hair. Composites are formed by combining materials together to form an overall structure with properties that differ from that of the individual components. A composite material (also called a composition material or shortened to composite, which is the common name) is ...
The Matrix is a 1999 science fiction action film [5] [6] written and directed by the Wachowskis. [a] It is the first installment in the Matrix film series, starring Keanu Reeves, Laurence Fishburne, Carrie-Anne Moss, Hugo Weaving and Joe Pantoliano, and depicts a dystopian future in which humanity is unknowingly trapped inside the Matrix, a simulated reality that intelligent machines have ...
In mathematics, particularly in linear algebra, matrix multiplication is a binary operation that produces a matrix from two matrices. For matrix multiplication, the number of columns in the first matrix must be equal to the number of rows in the second matrix. The resulting matrix, known as the matrix product, has the number of rows of the ...
If A is an m × n matrix and A T is its transpose, then the result of matrix multiplication with these two matrices gives two square matrices: A A T is m × m and A T A is n × n. Furthermore, these products are symmetric matrices. Indeed, the matrix product A A T has entries that are the inner product of a row of A with a column of A T.
