Talk:Streaming algorithm

computing over data streams is a recent phenomenon that is of growing interest in many areas of computer science, including databases, computer networks, and theory of algorithms. And streaming algorithms are the ones to solve problems in this scenario.

New Streaming Problem(s)

In the conclusion of, Every Microsecond Counts: Tracking Fine-Grain Latencies with a Lossy Difference Aggregator, Kompella et al. introduce a new streaming algorithm: two-party coordinated streaming with loss. My interpretation of this is: given a data stream and two synchronized nodes watching this stream, if there is some loss between N_1 and N_2 it becomes impossible for N_2 to accurately monitor the same stream. Their paper develops a method to ignore the losses and still provide answers with some probability of accuracy, but asks the question as to which coordinated functions can be computed with low memory.

I'm not sure if this is a developed enough idea to be presented on the actual wiki-page, nor do I understand this particular field well enough to be certain about my description. If someone more knowledgeable can add this information, please do. Sutekh.destroyer (talk) 20:12, 5 March 2010 (UTC)

Please clarify "Models" section

In the "Models" section it appears that two different sets of notation are used. One uses $a_{i}$ for incoming data while one uses $x_{i}$ - I might be mistaken and these might actually be intended as different things, but I believe they're referring to the same thing. Could someone please confirm this suspicion, and/or fix the section? Thanks --mcld (talk) 13:43, 30 April 2010 (UTC)

I think I've fixed the section, by dropping mention of the $x_{i}$. Basically, the $a_{i}$ are not necessarily the incoming data, but some vector you have in mind. For instance the incoming data may be a sequence of "updates" of the form $(i,c)$ meaning "increment $a_{i}$ by $c$". Shreevatsa (talk) 00:28, 17 July 2010 (UTC)

Redundant sections

The "5.1.1.1 Calculating F0 (Distinct Elements in a DataStream)" and "5.4 Counting distinct elements" sections could be merged as they talk about the same problem. — Preceding unsigned comment added by YassineMR (talk • contribs) 08:18, 18 October 2017 (UTC)

German Version

I tried to add a link to the German wiki (https://de.wikipedia.org/wiki/Datenstromalgorithmus) but I could not save it. Maybe somebody can fix this. --212.95.5.79 (talk) 08:30, 25 May 2020 (UTC)
