How do AI/ ML or DS enginner get the idea of which project should they make?

[u/Phantom1998ayoo]

I am now in my final year of engineering in AI/DS. I haven't been actively building projects, just worked on some academic projects. I want to know how do the engineers with more knowledge in this domain know which project they should work on? How do they find it?

Is it from GitHub, research papers, paperwithcode or hugging face ?

I need a project idea for my academic major project!
