Tetrad ii
| Глоссарий по искусственному интеллекту |
A multi-module program that uses path models and a bayesian network to construct and explore causal relationships in data. the program is based on an axiomatic connection between causal structure and statistical independence. see also: http://hss.cmu.edu/html/departments/philosophy/tetrad/tetrad.html

Relationships, английский
The lifestyle subcategory containing apps to help you with your personal relationships.
Connection, английский
- Liaison
- Соединение; связь
- In steel construction, a combination of joints capable of transmitting forces between two or more members. connector 1. in an electric circuit, a device for joining two or more conductors, by a low-resistance path, without the use of a permanent splice. 2. a mechanical device for fastening together two or more pieces, members, or parts, including anchors, fasteners, or wall ties.
- Патрубок с фланцевым соединением
- A link via wire, radio, fiber-optic cable, or other medium between two or more communications devices.
- Someone with whom a user has established a mutual social relationship on a third-party service that refers to such a relationship as a connection.
Statistical, английский
Independence, английский
- Г. индепенденс {шт. канзас, сша)
- Независимость
- In probabilistic expert systems, an attribute x is independent of another attribute y given a set of attributes w
- Self-suficiency concerning information. independent systems are closed to information. variation outside the boundaries of independent systems do not affect the variation within. there is no input. in statistics, two variables are independent if the coocurance of their values is mere chance, e.g., zero correlation. in logic and set theory, two variables are independent if the relation between them is the mere cartesian product of two properties. two individuals are independent if each does what he wants to do, neither having to consider the behavior of the other. a clock is designed to be independent of variation in temperature, geographical location including gravity while it is correlated with other clocks and communicating its output states to an observer. independent systems maybe a source but not the receiver of communication (->closed system, ->closure). .
Philosophy, английский
N философия language analytic(al) ~ аналитическая философия ordinary language ~ философия обыденного языка
Relationship, английский
- Отношение: соотношение; связь; взаимоотношение; взаимосвязь
- Отношение, степень родства
- A way in which someone or something is connected to another the incidence of the disease has a close relationship to the environment. he became withdrawn and broke off all relationships with his family.
- Зависимость, соотношение
- A connection between objects.
- A logical connection between entities.
- A smartart graphic layout type that includes layouts designed to illustrate connections.
- An association established between common fields (columns) in two tables. a relationship can be one-to-one, many-to-many, or one-to-many.
Department, английский
- Министерство; ведомство; управление; отдел
- A term by which the divisions in the public services are distinguished, as the civil, the commissariat, the military, the naval, the victualling, &c.
- An instance of parature that houses the data, files, and information for one client or organization. clients and organizations can have and operate multiple departments for various purposes and each department has its own segregated support portal by default. departments owned by the same client or organization are capable of sharing certain information; to learn more about sharing information between departments, consult the parature knowledgebase.

Simulated annealing, английский
A monte carlo based maximization/minimization technique used for complex problems with many parameters and constraints. it mimics the process of annealing, which starts with a high temperature mix of metal and slowly cools the mix, allowing optimal structures to form as the material cools. the simulated annealing procedure randomly generates a large number of possible solutions, keeping both good and bad solutions. these are randomly perturbed and can replace the existing solutions, even when the are worse. as the simulation progresses, the requirements for replacing an existing solution or staying in the pool becomes stricter and stricter, mimicking the slow cooling of metallic annealing. eventually, the process yields a small set of optimal solutions. see also: gibbs sampling, markov chain monte carlo methods. single instruction multiple datastream (simd) single instruction multiple datastream (simd) is a computer architecture, where there are multiple processors each performing the same set of computations on their own data. see also: multiple instruction multiple datastream.
Naive bayes, английский
A naive bayes classifier, like a bayes classifier, classifies on the basis of the predicted probabilities of the classes given the inputs. however, a naive bayes classifier treats the inputs as independent given the class, and estimates the distribution by simple counting, so that it is actually a frequentist approach. its general form is pr(classi | x) pr(classi) pj pr(xj | classi). it is also known as "simple bayes" or, more derisively, "idiot`s bayes." its performance can be improved by techniques such as boosting or augmented naive bayes classifiers. due to its simplicity, it is often used as reference point when comparing classifiers. as an example, suppose you have a d-category classification problem, with three binary predictors x1, x2, and x3, and you have a case with values 0, 1, and 1, respectively. then the naive bayes algorithm would score the d-th category as: p(d|0, 1, 1) p(d)p (x1 = o|d)p(x2 = 1|d)p(x3 = 1|d), where p(.|d) is the observed probability for the x value given the category. see also: bayes rule, boosting, tan bayes.
