Reducing Data Stream Sliding Windows By Cyclic Tree-Like ...
Value of the sliding window). The histogram is built on top of the sliding window, by hierarchically sum-marizing the values occurring in it. In order to describe the c-tree we chose a constructive fashion. In particular we define the initial configuration (at the time ... Get Doc
Fast Computation Of Approximate Biased Histograms On Sliding ...
Data distribution which the histogram must therefore model with greater accuracy. In this paper, after defining approximate biased histograms over sliding windows on data streams, we propose the Bar Splitting Biased Histogram (BSBH) algorithm to construct them efficiently and accurately. ...
