| Abstract | The wide application of local area communication system brings comprehensive data informa-tion but also increases the difficulty of data mining and analysis. Therefore, the data mining preprocessing link-attribute reduction is studied. The research is divided into three parts: first, the method of distinguished matrix fast calculating is used for discerning the core attributes of a data set; second, the k-nearest neighbor algorithm is used to calculate the attribute as well as the similarity coefficient between condition attributes, and to finish at the beginning of attribute reduction; and third, the global optimization ability of particle swarm algorithm im-plementation attribute reduction is used again to complete local area communication system incremental attribute reduction targets. The results show that compared with the three pre-vious reduction algorithms, the proposed algorithm has the least number of attributes and the least number of iterations, which proves the reduction degree and efficiency of the proposed method. |
