PLANAR MODEL AND ITS APPLICATION IN PREDICTION
Zhao Yang · Chinese Journal of Computers · 1998
Based on three technical mainstays, artificial intelligence, statistics and probability, database, a new research area, known as data mining and knowledge discovery (DMKD), has been established and has made a rapid development which offers lots of practical application systems aiding partial automation of data mining in large real databases. A new mathematical representation of linguistic concepts,which is called clouds model (CM), together with its theory, is presented in the paper. With the new model of clouds and a virtual rule engine, a novel uncertainty reasoning mechanism is proposed, and is used in the process of mining predictive knowledge. Based on the data clouds model, the concept of planar clouds is raised,as a more complex tool, it integrates fuzziness and randomness in an inseparable way. The digital characteristics of a planar clouds is represented by expected value Ex, entropy En and hyper entropy H. In the paper, the method of describing planar clouds is given, and the algorithm of the clouds is analyzed deeply, at last the application of planar clouds generators is discussed.
