Schema theorem
| Глоссарий по искусственному интеллекту |
A theorem showing that a genetic algorithm gives an exponentially increasing number of reproductive trials to above average schema. since each chromosome contains a great many schema, the rate of schema processing in the population is very high. see also: machine learning.

Schema, английский
- Same as body image scheuermann’s disease scheuermann’s disease / ????m?nz d? zi z/
- Схема
- A schema is a complete description of the attributes and allowable values of the attributes in a model. it can also include dependencies and relationships between the attributes. in genetic algorithms a schema is a template (such as a bit pattern with wildcards) that matches some genomes. see also: machine learning.
- An object or collection of database objects that contain structural information, or metadata, about a database.
- An xml text file that describes entity and relationship types. the schema also defines a container within which instances of these types are logically organized.
- The metadata used to describe the content and structure of a document.
- The set of definitions for the universe of objects that can be stored in a directory. for each object class, the schema defines which attributes an instance of the class must have, which additional attributes it can have, and which other object classes can be its parent object class.
- A form of microdata which, once added to a webpage, creates an enhanced description (commonly known as a rich snippet), which appears in search results.
Schema, французский
Schema (plural schemata), английский
A mental framework in which information is ordered and classified.
Schema cache, английский
A copy of the schema in memory to improve performance on schema operations. this cached version is automatically updated, in small time intervals, each time the schema is updated.
Schema constructif, французский

Schema mapping, английский
A special kind of transformation whereby an xml document is converted from one xml schema to another.
Schema master, английский
A domain controller that holds the schema operations master role in active directory. the schema master performs write operations to the directory schema and replicates updates to all other domain controllers in the forest. at any time, the schema master role can be assigned to only one domain controller in the forest.
Schema rowset, английский
A specially defined rowset that returns metadata about objects or functionality on an instance of sql server or analysis services. for example, the ole db schema rowset dbschema_columns describes columns in a table, while the analysis services schema rowset mdschema_measures describes the measures in a cube.
Schema snapshot, английский
A snapshot that includes schema for published tables and objects required by replication (triggers, metadata tables, and so on), but not user data.
Schema technologique, французский
Schema validation, английский
The verification that the xml of a procedure conforms to the provisioning schema of microsoft provisioning framework (mpf). this schema contains the generic xml elements and attributes available to invoke specific provisioning functionality.

Exponentially, английский
Экспоненциально; по экспоненте exponentially bounded algorithmалгоритм с экспоненциальной сигнализирующей
Increasing, английский
Chromosome, английский
- A rodshaped structure in the nucleus of a cell, formed of dna, which carries the genes comment: each human cell has 46 chromosomes, 23 inherited from each parent. the female has one pair of x chromosomes, and the male one pair of xy chromosomes, which are responsible for the sexual difference. sperm from a male have either an x or a y chromosome. if a y chromosome sperm fertilises the female’s ovum the child will be male.
- In genetic algorithms, this is a data structure that holds a sequence of task parameters, often called genes. they are often encoded so as to allow easy mutations and crossovers (i.e., changes in value and transfer between competing solutions). see also: crossover, gene, genetic algorithm, mutations.
- The structures in the nucleus of the cell, consisting of dna bound to histones and other proteins. the genes are made of dna (although most of the dna sequence is not part of any gene). genes are arranged along the chromosomes in a continuous sequence. chromosome protein structure allows for selective activation (genes are transcribed into protein) or silencing (genes are not expressed), and thus for differential expression of the genome in different cell types and expression of genes in appropriate sequences during the development of the organism or under various metabolic conditions.
- Bacteria genomic dna
- Discrete dna structure within a cell that controls cellular activities
Processing, английский
- Обработка (напр. данных); технология
- N обработка cognitive ~ когнитивная обработка language ~ когн.
- Обработка ~ of materials обработка [переработка] материалов
- A language originally designed for artists to allow them to do simple graphical design programs in a movie like paradigm.
- The preparation or packaging of fish to render it suitable for human consumption, retail sale, industrial use, or long-term storage, including but not limited to cooking, canning, smoking, salting, drying, filleting, freezing, or rendering into meal or oil, but not heading and gutting unless additional preparation is done.
- Under the gdpr, “processing” is any operation that is performed on personal data. this includes collection, recording, organisation, structuring, storage, adaptation, alteration, dissemination, erasure or destruction.
Population, английский
- A definable set of individual units to which the findings from statistical examination of a sample subset are intended to be applied. the population will generally much outnumber the sample. in re-randomisation statistics the process of applying inference
- See stock.
- A collection of units being studied. units can be people, places, objects, epochs, drugs, procedures, or many other things. much of statistics is concerned with estimating numerical properties (parameters) of an entire population from a random sample of units from the population.
- A group or number of people living within a specified area or sharing similar characteristics (such as occupation or age).
- Население; народонаселение; генеральная совокупность (в выборочном наблюдении); популяция (биол)
- Население
- 1. the number of people living in a country or town population statistics show that the birth rate is slowing down. the government has decided to screen the whole population of the area. 2. the number of patients in hospital the hospital population in the area has fallen below 10,000.
- Популяция
- Население; популяция -
- Популяция. в клинических исследованиях совокупность субъектов, обладающих какими-либо одинаковыми признаками (пол, возраст, диагноз).
- Население; популяция
- Any group of individuals, usually of a single species, occupying a given area at the same time; groups of organisms with homologue (same) alleles. p. cycle: changes in the numbers of individuals in a population which repeatedly oscillate between periods of high and low density. p. density: allowing a mathematically precise reflection - pd. • absolute: pd = number of individuals/unit area or volume [1/m2] or [1/m3] • relative: pd allows only a simple comparison (pd <, =, >, ? etc.). p. dynamics: the variations in time and space in the sizes and densities of populations; distribution due to changing food resources - the stability of a population depends upon abiotic factors, intraspecific competition (density dependent), natality, mortality etc. p. ecology: the study of the variations in time and space in the sizes and densities of populations, and of the factors causing those variations. p. fluctuation: variations over time in the size of a population. p. growth: is zero, when the birth rate equals the death rate (see carrying capacity). nt+1 = nt + r nt, current number of individuals r = (natality + immigration) - (mortality+emigration) r, intrinsic rate of growth (see density) p. pyramid: a means of illustrating the age structure of a population diagrammatically, by placing the youngest age class at the base and stacking successive age classes above it. p. regulation : a tendency in a population for some factor to cause density to increase when it is low and to decrease nt, momentary number of individuals when it is high. n0, number of individuals at start
- Generally, a collection of individuals with common characteristics. in statistics, a potentially infinite collection of independent (->independence) units that include all units of a specified type with attention paid only to the agggregate (->aggregation) property of the collection. a sample of data drawn from this population is a subset of the units constituting this population and scientific generalizations from such samples are limited by the size of the population originally specified (->model, ->representation).
- The process of scanning content to compile and maintain an index.
- Fish of the same species inhabiting a specified geographic area.

Signal state space, английский
A term used in the discussion of neural networks, a signal state space is the space defined by all possible outputs of model. if the model had one continuous bounded output, its state space would be that bounded interval. with two such outputs, the state space can form a rectangle with three a hyper-rectangle or cube, and so on.
Transformational grammar, английский
A theory for human languages that holds that any sentence in that language can be generated by a series of transformations on a basic set of sentences.
