摘要
Abstract
In response to time series of the sub-item sets, this paper presents a mathematical mechanism of model mining. Firstly a real-time frequency vector is set. For each item in the sub-item set, the average frequency of the items in the real-time vector is calculated and updated. A model checking period is selected, during which the Pearson correlation coefficients between the current real-time frequency vector and the ones in the model set are calculated. If one correlation coefficient is larger than the threshold, it is considered that this vector is enumerated in the model set. If the coefficient is smaller than the threshold, this vector is added into the model set and is considered as a new model. In the experiments, simulated data are used for evaluation of the algorithm from the theoretical point of angle. It also proves the pervasive attributes of such a algorithm. In the relevant security practice, the data from www. sina. -com are introduced and it is found that this algorithm is very effective for the Web security.关键词
