QUESTION - Does pyEMD, CEEMDAN try to account for end effects?

Open ctanny opened this issue 2 years ago • 2 comments

I am curious to know if there is anything in the package, specifically in the CEEMDAN class that addresses the end effects issues with EMD? Thanks.

Can you please elaborate what do you mean by "end effects issue with EMD?" EMD supports mirroring for time series beginning/end and CEEMDAN uses these algorithms when computing EMD. Is there anything else needed?

I'm not sure. I have been experimenting with regression and LSTM models to help reduce the end effects. But if mirroring reduces these issues and is incorporated into the CEEMDAN algorithm, then thanks! That's a huge potential problem that is dealt with. can you point me to where mirroring is discussed in the docs? Thank you for sharing this great work.
