Copulas in signal processing. A copula is a mathematical function that provides a relationship between marginal distributions of random variables and their joint distributions. Copulas are important because it represents a dependence structure without using marginal distributions. Copulas have been widely used in the field of finance, but their ...
Copula (statistics) In probability theory and statistics, a copula is a multivariate cumulative distribution function for which the marginal probability distribution of each variable is uniform on the interval [0, 1]. Copulas are used to describe/model the dependence (inter-correlation) between random variables. [1]
In linguistics, a copula /‘kɑpjələ/ (pl.: copulas or copulae; abbreviated cop) is a word or phrase that links the subject of a sentence to a subject complement, such as the word is in the sentence "The sky is blue" or the phrase was not being in the sentence "It was not being cooperative." The word copula derives from the Latin noun for a ...
The copula -i- in Korean is ubiquitously found in presumed ‘Sluicing’ and ‘Fragment’ constructions. The copula denotes the equative relation between the subject and the complement of the copula. In (8), through the assumed equative relation, the complement of the copula describes the ‘categorial membership’ of the subject.
Computational human phantoms are models of the human body used in computerized analysis. Since the 1960s, the radiological science community has developed and applied these models for ionizing radiation dosimetry studies. These models have become increasingly accurate with respect to the internal structure of the human body.
Computational linguistics is an interdisciplinary field concerned with the computational modelling of natural language, as well as the study of appropriate computational approaches to linguistic questions. In general, computational linguistics draws upon linguistics, computer science, artificial intelligence, mathematics, logic, philosophy ...
In computer science and computer engineering, computer architecture is a description of the structure of a computer system made from component parts. [1] It can sometimes be a high-level description that ignores details of the implementation. [2] At a more detailed level, the description may include the instruction set architecture design ...
Voxel-based morphometry is a computational approach to neuroanatomy that measures differences in local concentrations of brain tissue, through a voxel-wise comparison of multiple brain images. [ 1 ] [ 2 ] In traditional morphometry , volume of the whole brain or its subparts is measured by drawing regions of interest (ROIs) on images from brain ...
