bijection

Reservoir algorithm is used to sample from these single data stream respectively,then some multiple snapshot windows are constructed,the relationship between these single data stream and multiple snapshot windows is bijective mapping,the relationshi.

针对以元组为单位流入的具有相同属性集的多支单数据流组成的多数据流,提出了分别对每支单数据流进行蓄水池抽样,构造一一对应于各单数据流的若干个多快照窗口,即两者之间是双射关系,可以将多快照窗口串行置于主存中,将元组包含的属性与多快照窗口中的各个快照窗口一一对应,且使得同一快照窗口中的各基本窗口与取自其对应的单数据流的属性值样本一一对应,然后对这些相互独立的样本进行方差分析。
