Weighted Sampling From Landmark Windows Over Data Streams


There are growing interests in algorithms for processing and querying continuous data streams recently. This paper introduces the problem of sampling from landmark windows over data streams and presents a weighted stratified multistage sampling (WSMS) algorithm for this problem. The algorithm extends the classic reservoir-sampling algorithm and the weighted… (More)
