Sketching and streaming algorithms
WebbThe topic of this class is computation over data streams, and its various manifestations. A data stream is a sequence of data elements (numbers, geometric points, etc), which is much larger than the amount of available memory. The goal is to compute (perhaps approximately) some function of the data using only one pass1 over the data stream. http://keshavbashyal.github.io/blog/2015/12/19/data-stream-algorithms/
Sketching and streaming algorithms
Did you know?
WebbStreaming algorithms. Streaming algorithms have been an area of active research in the past 20 years, with both rich theories and many practical data stream systems developed. Several streaming models have been considered in the literature [22]: In the cash register model, each record in the stream inserts an element, and queries are asked on the Though streaming algorithms had already been studied by Munro and Paterson as early as 1978, as well as Philippe Flajolet and G. Nigel Martin in 1982/83, the field of streaming algorithms was first formalized and popularized in a 1996 paper by Noga Alon, Yossi Matias, and Mario Szegedy. For this paper, the authors later won the Gödel Prize in 2005 "for their foundational contribution to streaming algorithms." There has since been a large body of work centered around data streami…

In this invited talk, we will survey some of the recent work on designing algorithms for analyzing massive graphs. Such graphs may not fit in main memory, may be distributed across numerous machines, and may change over time. This has motivated a rich body of work on analyzing graphs in the data stream model and the …

Again this follows because the linearity of the sketches ensures that by adding together the sketches of the partial streams, we get the sketch of the entire stream. fatmagül 94 rész magyarul videa
