cophenetic calculation for rank estimation

[yoshihiko1218]

Hi,

I am now trying to integrate nmf with ability to automatically detect the rank into my program. However, when I tried to get cophenetic to estimate the best rank, they are all 1. I saw another issue and learned that it wan ran only on one model so it's giving 1. However, I could not figure out how should I modify the code to make it work. I wonder if there is any template or tutorial for rank estimation?

Thank you

I also didn't find the multiple run parameter, but in the documents, they mentioned this several times.
Did you solve this problem

Here is a good example for rank estimation: https://github.com/mims-harvard/nimfa-ipynb
