Data Generalization

entropy Generalization And thought explanation ask forgeing The retrieval of info from informationbases, and the transmission line of kernel functions ( such as summation, counting, etc.) to the information represent an historic functionality of entropybase systems. However, dubiousness bear uponing is non entropy digging. Query processing: Retrieves tags of data from databases and can compute aggregate functions on the retrieved data. Data excavation: analyzes the data and discovers interesting patterns transcendental in the database. What is concept rendering? A concept ordinarily refers to a collection of data such as stereos, general buyers, graduate students, and so on. As a data mining task, concept description is not a simple record of the data. Instead, it generates descriptions for characterization and comparison of the data. fancy description is sometimes called line description when the concept to be described refers to a trend of objects. Characterization provides a brief and brief summarization of the give collection of data. Concept or class comparison (also cognize as discrimination) provides descriptions comparing deuce or more collections of data. What is Data generalization?

Is a process which abstracts a large set of task-relevant data in a database from a relatively beginning conceptual level to noble conceptual levels. Concept description has close ties with data generalization. given over the large amount of data stored in databases, it is useful to be able to describe concepts in brief terms at generalised (rather than low) levels of abstract entity. eitherowing data sets to be generalized at two-fold levels of abstraction facilitates users in examining the general manner of the data. EXAMPLE: effrontery the All Electronics database, for example, instead of examining individual node transactions, sales managers may privilege to view the data generalized to higher levels, such as summarized by customer groups...If you command to get a encompassing essay, order it on our website: Ordercustompaper.com
