研究多流時序不能簡單地將它割裂為單流時序,因為這樣就割裂了數據流事件之間的關系。雖然msdd能夠發現多流時間序列中的依賴模式,但是由於其缺少對數據的初始化、事件之間時間關系的表示不直觀、演算法執行的時間空間開銷很大( o ( n ~ 5 ) ) 、不能夠充分發現多流時間序列包含的知識,它只發現依賴關系,因此研究新的,高效,全面的發現多流時間序列事件之間關系的演算法成為必要。本文分析了單一和多流時間序列中的知識發現,把多流時間序列事件內部存在的關系表示為:關聯模式、依賴模式、突變模式。Ptwma is an effective successful algorithm and model to the knowledge discovery of the multiple streams time series

本文將它們統稱為結構模式,而這正是目前其它演算法、沒有考慮到的,雖然msdd考慮了事件之間的依賴關系,但它忽略了突變模式,關聯模式等重要的知識表示。本文給出了關聯模式、依賴模式、突變模式的定義,提出了一個比較靈活全面、直觀的挖掘它們的演算法:時間窗口移動篩選演算法twma ( timewindowmovingandfilteringalgorithm ) 。該演算法的一個突出特點是將時間序列事件按時間窗口序列化,使得事件之間的時間關系表示很直觀,該演算法能成功地從多流時間序列中發現了事件之間的關系。These researches will help us to discover changing or developing principle of things, support to decision - making, etc. the thesis addresses several key technical problems of pattern mining and its search based similarity in time series, which covers feature patterns and relationship patterns mining, pattern search based on similarity in time series and stream time series and issues concerning application system implementation oriented to analysis. major contributions of this thesis include : 1. research of mining feature patterns in time series a novel method is proposed to discovery frequent pattern from time series
