iSAX 2.0: Indexing and Mining One Billion Time Series [pdf] (cs.ucr.edu) 26 points by chaotic-good 10y ago ↗ HN
[–] jcr 10y ago ↗ This iSAX 2.0 paper seems to be from 2010, so the HN title should probably be changed.The first iSAX paper was from 2008, and there's a page here about it:http://www.cs.ucr.edu/~eamonn/iSAX/iSAX.htmlThe list of "selected" publications by Eamonn Keogh is a whole lot of fun:http://www.cs.ucr.edu/~eamonn/selected_publications.htm [–] chaotic-good 10y ago ↗ iSAX was an improvement over simple SAX indexing scheme that was known since 2005 or so. [–] jcr 10y ago ↗ My failing meatware recollection said 2001-ish, maybe earlier, but it seems I'm wrong according to this:http://www.cs.ucr.edu/~eamonn/SAX.htm>"SAX was invented by Eamonn Keogh and Jessica Lin in 2002, using funding from NSF Career Award 0237918."

[–] cbsmith 10y ago ↗ Interesting coincidence. We just went over this paper last month in our white paper group.
[–] ppyil 10y ago ↗ Does anyone know of any code for iSAX that isn't in C# or Java? I'd quite like to get stuck in but right now I'm using Python. I've got SAX set up but getting the iSAX indexing will take some time. [–] travisbrady 10y ago ↗ Both of these appear to do what you want:- https://github.com/dolaameng/pysax - https://github.com/nphoff/saxpy [–] ppyil 10y ago ↗ Thank you. These are great for SAX but unfortunately don't implement iSAX. I'm working on iSAX for Python and will release that once it is complete.

The list of "selected" publications by Eamonn Keogh is a whole lot of fun:
