中文摘要：
设计了数据流预测查询的新模型，包括局域流能量预测、能量分布模式挖掘及预测序列的重构和数据流能量的度量方法；设计了融合数据流能量回归与基于频繁模式的小波分解预测新方法，并将新算法推广到强偶合多数据流的预测查询；提出了最近最频繁序列模式的新概念，并应用于局域流能量分解；在真实数据上的模拟实验，验证了算法的有效性．
英文摘要：
A new predict model was contrived, which involves local stream energy prediction, the energy distribution pattern mining, the predictive series reconstruction and measurement method of stream energy. A new method was designed to forecast stream by energy regression and wavelets decomposing based on frequent pattern, and extended to multi-streams with strong coincidence. The concept of the nearest maximum frequent pattern was proposed to decompose local stream energy. The validity of new algorithm was demonstrated by extensive experiments on real data.
