[D] Looking for advice regarding shortage of references for comparison in my research work

I’m working in machine learning- application field. There are very few references which apply machine learning framework in my field of interest. So, even if I have comparison results of our framework with one baseline, I am unable to find more methods that solve the problem I am interested in.

I see there is an in-depth comparision analysis provided in the machine learning conference papers. How to manage my analysis work with very few comparison results? I can perform additional experiments in even higher dimensions, but other than that, I’m unsure how to proceed from there.

I would appreciate any advice and suggestions to move forward in such situation. Thank you in advance.
