improvement of the R-factor by adjustment of the model to better agree with the measured data There are limits as to how close the model must be before a refinement method can find a better structure This is the radius of convergence
The revision of one or more descriptions as a result of discussion Refinements include the creation of new descriptions that are either subordinate to existing descriptions or otherwise dependent on them
a highly developed state of perfection; having a flawless or impeccable quality; "they performed with great polish"; "I admired the exquisite refinement of his prose"; "almost an inspiration which gives to all work that finish which is almost art"--Joseph Conrad
application of a transformation step to some software workproduct (a model or code) to produce a more detailed, less generic and less abstract software product
An constructor operation that builds a term from another (already defined) term The constructed term has a root with constituent the identifier of the root of the original term For instance an alien person from Mars (the PC way to say Martian) can be refined from person as follows: (define (person Martian) (planet Mars)) The root is Martian and has person as constituent Refinement permits overriding, and in the example Martian overrides planet to be Mars--when formerly had been Earth Thus, refinement does not imply subsumption See §2 2 2
An alignment of every category of an ontology A to some category of another ontology B, which is called a refinement of A Every category in A must correspond to an equivalent category in B, but some primitives of A might be equivalent to nonprimitives in B Refinement defines a partial ordering of ontologies: if B is a refinement of A, and C is a refinement of B, then C is a refinement of A; if two ontologies are refinements of each other, then they must be isomorphic
Or sharpness, only applies to probability forecasts and is the extent to which an individual forecast differs from the overall average forecast It is related to the forecast marginal distribution, p(f), and can also be thought of as the degree to which probability forecasts approach categorical forecasts of 0 or 1
Refinements are small changes or additions that you make to something in order to improve it. Refinement is the process of making refinements. Older cars inevitably lack the latest safety refinements
a subtle difference in meaning or opinion or attitude; "without understanding the finer nuances you can't enjoy the humor"; "don't argue about shades of meaning"
A relationship that represents the fuller specification of something that has already been specified at a certain level of detail For example, a design class is a refinement of an analysis class
A refinement is a dependency within which the source is at a finer degree of abstraction than the target You model a refinement using the refine keyword
A relationship that represents a fuller specification of something that has already been specified at a certain level of detail For example, a design class is a refinement of an analysis class
(v) A repetitive process (iterative or cyclical) used to test the preliminary design, make changes if necessary, and determine if the design meets the goals of the project Models are used to analyze and visualize the design Refinement drawings are used to analyze the design in its current stage of the design process
In the context of sensemaking, refinement is a sensemaking operation that purifies and possibly grades information The term is used in an analogy to the mining and refining of ore or oil An oil refinery removes impurities from the crude oil It can also split the oil into different grades -- which are used for different purposes Information refining produces enriched information See also document mining and sensemaking operations
