Master's degreeA master's degree (from Latin magister) is a postgraduate academic degree awarded by universities or colleges upon completion of a course of study demonstrating mastery or a high-order overview of a specific field of study or area of professional practice. A master's degree normally requires previous study at the bachelor's level, either as a separate degree or as part of an integrated course.
Matrice (mathématiques)thumb|upright=1.5 En mathématiques, les matrices sont des tableaux d'éléments (nombres, caractères) qui servent à interpréter en termes calculatoires, et donc opérationnels, les résultats théoriques de l'algèbre linéaire et même de l'algèbre bilinéaire. Toutes les disciplines étudiant des phénomènes linéaires utilisent les matrices. Quant aux phénomènes non linéaires, on en donne souvent des approximations linéaires, comme en optique géométrique avec les approximations de Gauss.
Sample mean and covarianceThe sample mean (sample average) or empirical mean (empirical average), and the sample covariance or empirical covariance are statistics computed from a sample of data on one or more random variables. The sample mean is the average value (or mean value) of a sample of numbers taken from a larger population of numbers, where "population" indicates not number of people but the entirety of relevant data, whether collected or not. A sample of 40 companies' sales from the Fortune 500 might be used for convenience instead of looking at the population, all 500 companies' sales.
ParameterA parameter (), generally, is any characteristic that can help in defining or classifying a particular system (meaning an event, project, object, situation, etc.). That is, a parameter is an element of a system that is useful, or critical, when identifying the system, or when evaluating its performance, status, condition, etc. Parameter has more specific meanings within various disciplines, including mathematics, computer programming, engineering, statistics, logic, linguistics, and electronic musical composition.
Engineer's degreeAn engineer's degree is an advanced academic degree in engineering which is conferred in Europe, some countries of Latin America, North Africa and a few institutions in the United States. The degree may require a thesis but always requires a non-abstract project. Through the Canadian Engineering Accreditation Board (CEAB), Engineers Canada accredits Canadian undergraduate engineering programs that meet the standards of the profession.
Théorie de l'estimationEn statistique, la théorie de l'estimation s'intéresse à l'estimation de paramètres à partir de données empiriques mesurées ayant une composante aléatoire. Les paramètres décrivent un phénomène physique sous-jacent tel que sa valeur affecte la distribution des données mesurées. Un estimateur essaie d'approcher les paramètres inconnus à partir des mesures.
HermitienPlusieurs entités mathématiques sont qualifiées d'hermitiennes en référence au mathématicien Charles Hermite. Produit scalaire#Généralisation aux espaces vectoriels complexesProduit scalaire hermitien Soit E un espace vectoriel complexe. On dit qu'une application f définie sur E x E dans C est une forme sesquilinéaire à gauche si quels que soient les vecteurs X, Y, Z appartenant à E, et a, b des scalaires : f est semi-linéaire par rapport à la première variable et f est linéaire par rapport à la deuxième variable Une telle forme est dite hermitienne (ou à symétrie hermitienne) si de plus : ou, ce qui est équivalent : Elle est dite hermitienne définie positive si pour tout vecteur .
Consistent estimatorIn statistics, a consistent estimator or asymptotically consistent estimator is an estimator—a rule for computing estimates of a parameter θ0—having the property that as the number of data points used increases indefinitely, the resulting sequence of estimates converges in probability to θ0. This means that the distributions of the estimates become more and more concentrated near the true value of the parameter being estimated, so that the probability of the estimator being arbitrarily close to θ0 converges to one.
Asymptotic analysisIn mathematical analysis, asymptotic analysis, also known as asymptotics, is a method of describing limiting behavior. As an illustration, suppose that we are interested in the properties of a function f (n) as n becomes very large. If f(n) = n2 + 3n, then as n becomes very large, the term 3n becomes insignificant compared to n2. The function f(n) is said to be "asymptotically equivalent to n2, as n → ∞". This is often written symbolically as f (n) ~ n2, which is read as "f(n) is asymptotic to n2".
Double degreeA double degree program, sometimes called a dual degree, combined degree, conjoint degree, joint degree or double graduation program, involves a student working for two university degrees —either at the same institution or at different institutions, sometimes in different countries. The two degrees might be in the same subject area, or in two different subjects. Undergraduate Brunei – Sultan Sharif Ali Islamic University Provide a double degree for Bachelor of Laws (LL.
