Research on Mixed Attribute Data Clustering Method based on Generalized Linear Model

To solve the problem of high difficulty in data clustering of mixed attributes, this paper proposes a method of data clustering of mixed attributes based on generalized linear model. Firstly, a low-order multivariate generalized linear model is constructed to deal with the problem of massive data clustering. For these prototypes, the time series matrix of the attributes was considered. Finally, considering the distance between samples and the clustering center, the known sample information content is taken into account. The data dissimilarity and the distance between samples and clustering sets are calculated by using the optimization method. When the clustering results tend to be stable, the operation is terminated and the clustering results are output. To test based on generalized linear model of mixed attribute data clustering method about the effectiveness of experimental analysis, the results showed that the method with less iteration optimization can be divided mix attribute data clustering set, clustering fitness values between 0.88 ~ 0.94, fitness, and this method can accurately reflect differences between samples, is a kind of mixed attribute data clustering method of high accuracy.
