Shannon's diagram of a general communications system, showing the process by which a message sent becomes the message received (possibly corrupted by noise). seq2seq is an approach to machine translation (or more generally, sequence transduction) with roots in information theory, where communication is understood as an encode-transmit-decode process, and machine translation can be studied as a ...
The abstraction operator, λ, is said to bind its variable wherever it occurs in the body of the abstraction. Variables that fall within the scope of an abstraction are said to be bound. In an expression λx.M, the part λx is often called binder, as a hint that the variable x is getting bound by prepending λx to M. All other variables are ...
The term abstraction has a number of uses in the field of linguistics. It can denote a process (also called object abstraction) in the development of language, whereby terms become used for concepts further removed from the objects to which they were originally attached. It can also denote a process applied by linguists themselves, whereby ...
The state (polity) as both concept and material practice exemplifies the two sides of this process of abstraction. Conceptually, 'the current concept of the state is an abstraction from the much more concrete early-modern use as the standing or status of the prince, his visible estates'.
The theorem does not describe an actual theorem that can be proven; rather, it is a general principle for managing complexity through abstraction. The theorem is often expanded by the humorous clause "…except for the problem of too many levels of indirection", referring to the fact that too many abstractions may create intrinsic complexity ...
In a rule-based machine translation system the original text is first analysed morphologically and syntactically in order to obtain a syntactic representation. This representation can then be refined to a more abstract level putting emphasis on the parts relevant for translation and ignoring other types of information.
An abstraction representing a set of instructions that can be applied to input data to produce output. Central to procedural and functional programming; present in all programming paradigms. Algorithm: A step-by-step procedure or formula for solving a problem. Fundamental for algorithm design and analysis in various domains. Data type
Abstraction is used to allow for generalized answers to questions (for example, answering "maybe" to a yes/no question, meaning "yes or no", when we (an algorithm of abstract interpretation) cannot compute the precise answer with certainty); this simplifies the problems, making them amenable to automatic solutions. One crucial requirement is to ...
