question

It would be nice to add a tutorial(s) that reproduces the [Matrix Profile Top Ten](https://github.com/TDAmeritrade/stumpy/files/4446948/zhu2020.pdf) paper. The accompanying data at their Google sites page can be [found here](https://sites.google.com/site/matrixprofiletopten/). It might...

help wanted
good first issue
documentation enhancement

An initial tutorial has already been created [here](https://github.com/TDAmeritrade/stumpy/blob/main/docs/Tutorial_Pan_Matrix_Profile.ipynb) We need to add a final example where there are [two different window sizes within the same dataset](https://arxiv.org/pdf/1802.04883.pdf). The data can be...

documentation enhancement

Currently, `stumpy.stump` and `stumpy.stumped` can account for constant regions. So, when two subsequences are being compared and one subsequence is constant (and the second is not constant) then the pearson...

enhancement

As our test suite gets longer, the `coverage` tests, which are executed in pure Python, will continue to need more time to complete. GIven that Github Actions has a job...

testing

As we move toward supporting top-k matrix profiles, we need to ensure consistency of our outputs and they need to be 2D instead of 1D. This is related to #592...

enhancement

Currently, functions like `stump`, `stumped`, and `gpu_stump` only return the top-1 nearest neighbor. Depending on the added complexity, we may want to consider adding a top-K nearest neighbor matrix profile....

enhancement

For non-normalized methods, add top-k matrix profile capability. This is related to #592 and #640

enhancement

In some functions like, `core.mass` or `motifs.match`, it is possible to supply an optional `T_subseq_isfinite` parameter IFF `normalize=False`. Therefore, we should add a note to the `normalize` docstring to express...
