I am currently an undergraduate, wanting to apply to PhD programs this upcoming fall. So I started talked to a CS professor doing research in deep learning and he set me up to work with one of his graduate students, so I started to work with the grad student and only communicated with him, not the professor. I recently came up with a new idea for a model to be published that the grad student thinks is a good idea, but he told me he has left working with the professor and no longer is working on this research.
So I am at a crossroads on what to do. I have an idea that was told could be good, but I have no idea what the process looks like for self-publishing and expected that the grad student would be there to help me. I thought about reaching out the professor, but I am not sure what to say, since the grad student left, the project is essentially dead I think so it is more of just me having a new idea and not sure how the professor could help with it.
Any advice on whether I should reach out to the professor or just try to work on it on my own would be greatly appreciated.
