Description
Suggested estimator for time series annotation - changepoints and segments.
The algorithm is simple and ensures that episodes, i.e., segments, or time differences between change points, are larger than a given minimum.
A simple algorithm proceeds as follows:
- for each segment: check whether length is smaller than
min_length; if yes, merge with the next segment, and change labels to the majority of the two. - repeat 1 until no too short segments are found
This is just one possible strategy to do this, another one proceeds as follows:
Loop over segments, shortest first. For each segment, if too short, split in the middle and merge with adjacent segments. Update ordering of lengths each time this is done, until no too short segments remain.
The syntax would be that of a compositor: EnsureMinLengthSegments(my_annotator, strategy="strategyname")
