It looks like FLIP-39 is only partially implemented as for now , so I’m not sure which features are already done. I’m including Shaoxuan Wang in this thread, maybe he will be able to better answer your question.
I'm a cs student currently working on my Bachelor's thesis. I've
used Flink to extract features out of some datasets, and I would like to
use them together with another dataset of (1,0) (Node exists or doesn't)
to perform a logistic regresssion. I have found that FLIP-39 has been
accepted and it is running in version 1.10.0 that I also currently use,
but I'm having trouble implementing it. Are there any java examples
currently up and running? Or if you can propose a different way to perform the task?
