Can STUMPY/matrix profile be used for non-time series data? #318

@SultanOrazbayev Welcome to the STUMPY community and thank you for your question. So, technically, matrix profiles operate on sequential data and does not explicitly use "time" in its computation of the matrix profile. While it is somewhat assumed that your data is recorded on a regular interval, STUMPY does not complain if your data isn't actually from a regular interval (as it has no knowledge of this information). Thus, if you provide data that is not sampled on a regular interval then it is the user's responsibility to keep that in mind when interpreting the results. You can either try analyzing your data as-is OR aggregate up to common interval. In fact, I recommend just trying both and looking at the results. Hopefully, if your data isn't too big then this should be a reasonably quick analysis. I'd be happy to discuss this more or let me know if this makes sense? |

I haven't read the theory/math behind the matrix profile, so I apologise if this is a silly question, but can STUMPY/matrix profile be used for non-time series data? My guess is that the underlying data must be sequential and regular, but what happens if the data is sequential, but not recorded at a regular interval?
