Filter And Refine
Filter and Refine Principle (FRP) is a general computational strategy in computer science. FRP is used broadly across various disciplines, particularly in information retrieval, database management, and pattern recognition, which efficiently processes large sets of objects through a two-stage approach: filtering and refinement. The filtering stage quickly eliminates less promising or irrelevant objects from a large set using efficient, less resource-intensive algorithms. This stage is designed to reduce the volume of data that needs to be processed in the more resource-demanding refinement stage. Following filtering, the refinement stage applies more complex and computationally expensive techniques to the remaining objects to achieve higher accuracy via finer-grained processing. This stage is essential for obtaining the desired quality and precision in the results. FRP is a general method for completing a computationally intensive task as quickly as possibleFilter and Refine S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computer Science
Computer science is the study of computation, information, and automation. Computer science spans Theoretical computer science, theoretical disciplines (such as algorithms, theory of computation, and information theory) to Applied science, applied disciplines (including the design and implementation of Computer architecture, hardware and Software engineering, software). Algorithms and data structures are central to computer science. The theory of computation concerns abstract models of computation and general classes of computational problem, problems that can be solved using them. The fields of cryptography and computer security involve studying the means for secure communication and preventing security vulnerabilities. Computer graphics (computer science), Computer graphics and computational geometry address the generation of images. Programming language theory considers different ways to describe computational processes, and database theory concerns the management of re ...

Classification
Classification is the activity of assigning objects to some pre-existing classes or categories. This is distinct from the task of establishing the classes themselves (for example through cluster analysis). Examples include diagnostic tests, identifying spam emails and deciding whether to give someone a driving license. As well as 'category', synonyms or near-synonyms for 'class' include 'type', 'species', 'order', 'concept', 'taxon', 'group', 'identification' and 'division'. The meaning of the word 'classification' (and its synonyms) may take on one of several related meanings. It may encompass both classification and the creation of classes, as for example in 'the task of categorizing pages in Wikipedia'; this overall activity is listed under taxonomy. It may refer exclusively to the underlying scheme of classes (which otherwise may be called a taxonomy). Or it may refer to the label given to an object by the classifier. Classification is a part of many different kinds of activ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Network Planning And Design
Network planning and design is an iterative process, encompassing #A network planning methodology, topological design, #A network planning methodology, network-synthesis, and #A network planning methodology, network-realization, and is aimed at ensuring that a new telecommunications network or service meets the needs of the subscriber and network operator, operator.Penttinen A., ''Chapter 10 – Network Planning and Dimensioning, Lecture Notes: S-38.145 - Introduction to Teletraffic Theory'', Helsinki University of Technology, Fall 1999. The process can be tailored according to each new network or service.Farr R.E., ''Telecommunications Traffic, Tariffs and Costs – An Introduction For Managers'', Peter Peregrinus Ltd, 1988. A network planning methodology A traditional network planning methodology in the context of business decisions involves five layers of planning, namely: * need assessment and resource assessment * short-term network planning * IT resource * long-term and m ...
