samplingalgorithmsIn this paper, we resolve the one-pass space complexity of perfect L-p sampling for p is an element of (0, 2) in a stream. Given a stream of updates (insertions and deletions) to the coordinates of an underlying vector f is an element of in Rn, a perfect L-p ...
Part of that is the challenge of making sense of data, and helping scientists find answers to their questions," he says. “I’ve always been interested in how much the character of a stream can change over time or after a large storm,” continues Dow. “The average layperson thinks ...
This section provides a detailed description of the AXI4-Stream user-side interface. This interface must be used by the user-side logic to initiate frame transmission and accept frame reception to and from the core. The definitions and abbreviations used in this chapter are described in the ...
Stream sampling is the process of collecting a representative sample of the elements of a data stream. The sample is usually much smaller than the entire stream, but can be designed to retain many important characteristics of the stream, and can be used to estimate many important aggregates on...

We present three algorithms to count the number of distinct elements in a data stream to within a factor of 1 ±ε. Our algorithms improve upon known algorithms for this problem, and offer a spectrum of time/space tradeoffs. Part of this work was done while the author was visiting IBM Alm...
Big data has a substantial role nowadays, and its importance has significantly increased over the last decade. Big data’s biggest advantages are providing knowledge, supporting the decision-making process, and improving the use of resources, services, a
