# 1 - STUMPY Basics
|
|
Above what was seen in the tutorial I started on a generalized motif and discord
|
|
extraction procedure. Since these are both really the same process over different
|
|
sort orders of the matrix profile we end up with a very clean functional setup
|
|
with a single function doing all the work and two wrappers 'deciding' which
|
|
calculation should be done. This allowed me to generalize marking discovered
|
|
discord and motif windows on my output plots, a process which should remain more
|
|
or less evergreen.
|
|
|
|
## TODO
|
|
I remember reading that the distances returned by a matrix profile have an upper
|
|
bound. I should see what calculating my distance cutoff with that upper bound
|
|
looks like rather than calculating off the top motif like I do now.
|
|
|
|
If two motifs overlap it could be that the window is too small. I don't know what
|
|
other criteria to test yet to tell me if that is the case or not. I do know that
|
|
this can be determined in discovery stages using a Pan-matrix profile (PMP).
|
|
|
|
Some form of reference following should occur to ensure that I'm grabbing motifs
|
|
which actually relate to one another.
|
|
|
|
Currently the function is quite primitive. It should be packaged and iterated on
|
|
using the data in further sections of the tutorial. |
