  1. We ca n ' t divide the multiple streams time series into singleness times series simply in the research of multiple streams time series, we ' ll dissever the relation between the events of the multiple streams. although the msdd can find the dependency relationship of multiple streams, but it have n ' t the initialization of the events, the express of the time relationship between events is not frank, the cost of the algorithm is expensive ( o ( n5 ) ), i ca n ' t find much more knowledge in multiple time series, it find the dependency patterns only of the multiple time series, so there need a new more effective, frank, complete algorithm to find the knowledge

    研究多不能簡單地將它割裂為單,因為這樣就割裂了數據事件之間的關系。雖然msdd能夠發現多時間中的依賴模式,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 ) ) 、不能夠充分發現多時間包含的知識,它只發現依賴關系,因此研究新的,高效,全面的發現多時間事件之間關系的演算法成為必要。本文分析了單一和多時間中的知識發現,把多時間事件內部存在的關系表示為:關聯模式、依賴模式、突變模式。
  2. This paper analysis the data mining of the single nd multiple streams time series, and draw a conclusion that the relationship between the events of the multiple streams time series are the association patterns dependency patterns, sudden patterns, this paper call them are structure patterns, the existing algorithm have n ' t discuss these patterns, although msdd discussed the dependency patterns, however, it ignored the association patterns, sudden patterns, this paper have a definition of the association patterns, sudden patterns and dependency patterns, and have a complete, frank algorithm called twma ( time window moving and filtering algorithm ), the peculiarity of this algorithm is that events is listed by the time window, by this way, the relationship of the events is clear

    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、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事件按時間窗口化,使得事件之間的時間關系表示很觀,該演算法能成功地從多時間中發現了事件之間的關系。
