The Study on Gray Data Mining Model

摘要

Nowadays, most people rely on traditional data mining techniques to address business affairs. But data mining is proposed for the large amount of data, lack of effective methods to process the data that is little or incomplete, or is overall complex but has a strong regularity at a certain time or space. Grey system theory is the new method to research less data, poor information and uncertainty problem. It just makes up for the shortcomings of traditional data mining. Therefore, this paper is to combine gray system theory with data mining technology, study and improve the gray relational data mining model, and as the basic for the establishment of a gray clustering mining model. At last, this paper applies the gray data mining model to the comparison of the securities companies' core competitiveness, thus proving the correctness and effectiveness of the model.
