Hi, thanks for sharing this repo!
I am reading your code and am curious why we need to transform all values to be positive when computing singular values here:
? Thanks!Hello,
can you please provide details on SingularSpectrumTransformation's parameters? Is there some recommendations how to choose win_length, order, lag? What does 'order' signify?
E.g. in "Change-Point Detection in Time-Series Data based on Subspace Identification by

parameters for experiment in 5.1 were selected as tau=150, k=8, N=150, N=80 and n=2. How should I set up parameters in your function when I want to re-make given experiment?
Thank you.
