| 摘 要： | 针对当前XML数据流质量检测存在的不足,提出了一种自适应的XML数据流质量预测方法XAFS。该方法用XML键构建的矢量矩阵作为窗口、利用矢量积小波变换多级分解与重构XML数据流、再结合最小二乘支持向量机对XML数据流质量进行预测;为了更好的适应网络负载,采取加权与自适应窗口调整等调度策略充分保证XML数据流的质量检测。对比其它相应算法,一系列仿真实验表明所提出算法具有较高的精度与实用性,是XML数据流挖掘的一种有效方法。

| Abstract: | Aimed at the currently shortage of XML streams quality detecting,an adaptive quality forecasting method of XML data streams(XAFS) is presented.It uses the vector matrix built by the XML keys as windows,uses vector product wavelet transform to multilevel decompose and refactor the XML streams series,and then forecasts the XML streams’ quality combing squares support vector machines.For even more adapting net load,it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.Contrasting with other corresponding algorithms,a series of emulation experiments shows that this method has proper rather precision and practicability,so it is an effective forecasting method of XML streams mining. |
