Recently I submitted an IEEE conference paper about an open-source machine learning project/framework related to mobile networks. Now, I also want to demonstrate its features at another IEEE conference using a 2-page demo paper.
Considering the original paper is still in reviewing process, is it ethical to submit a related demonstration paper with the same approach to another conference. I mean from self-plagiarism aspects, can I use the same title and experiment results in demo paper as well just for showcasing purposes? If not, how can I also reference the original paper considering it is not published/accepted yet!
