Support for multivariate time series about matrixprofile-ts

[vanbenschoten]

Hi Marcelo,
It's a non-trivial addition, but do-able (we just haven't had the bandwidth to incorporate it yet). We'll hopefully include it in the near future, though you're always welcome to submit your own PR :) In the meantime, the other two libraries supported by the Matrix Profile Foundation (go-matrixprofile (Golang) and tsmp (R)) have multivariate capabilities.

Sweet, gonna have a look at that ones. Thank you for the quick reply!

@ortegatron You can also take a look at this paper for multivariate mp. https://www.cs.ucr.edu/~eamonn/Motif_Discovery_ICDM.pdf.

great code thanks
may you still clarify :
will it work for multivariate time series as written in Matrix Profile VI: Meaningful Multidimensional
Motif Discovery
https://www.cs.ucr.edu/~eamonn/Motif_Discovery_ICDM.pdf.
1
where all values are continues values
2
or even will it work for multivariate time series where values are mixture of continues and categorical values
for example 2 dimensions have continues values and 3 dimensions are categorical values

@Sandy4321 unfortunately this library is no longer maintained. I'd recommend you take a look at the Matrix Profile Foundation's new library here. It's substantially more performant than matrixprofile-ts, and includes a number of additional features (pan-Matrix Profile, Snippets support, etc).

With respect to your original question, the matrixprofile library has an open issue to add multi-dimensional support in the near future. Feel free to add to the discussion there, as well as submit a PR :)
