UCR Time Series Classification Archive

Last major update, Fall 2018: Early work on this data resource was funded by an NSF Career Award 0237918, and has been funded through NSF IIS-1161997 II and NSF IIS 1510741.

Call for sponsorship: Maintaining this (and the multidimensional) archive requires effort that is not currently funded. We seek a sponsor who would be willing to pay a few k per year to keep these sites up to date.

This is the beta version of the new archive. We welcome suggestions and corrections. We will turn it into a final release at the end of December 2018. In the mean time, you can still access the old archive. If you do independent test that confirm/contradict our results, please let us know.  

We suggest you begin by reading the briefing document in PDF or PowerPoint, which also contains the password. Then you can download the entire archive (about 260 MB in zipped format).

We recommend you to read this paper for a detailed discussion of how the community can best benefit from the archive. If you are interested in multivariate (multi-dimensional) time series, there is a collection of thirty such datasets archived here: www.timeseriesclassification.com, read this paper for details.

Fun fact: We estimate that to build this archive we needed to invoke DTW 321,053,852 times at testing time, and 61,041,100,000,000 times at training time (learning the warping window width). Yet, to this day there are still papers that bemoan that the “DTW is too slow…” If you think that, check out the UCR Suite.
