I am researching machine learning models for predictability, and I am doing a literature survey/review right now.
Can I use research papers from non computer-science journals in my proposals?
For instance, I am using machine learning to predict X. The reason why X should be predicted and the 'state-of-the-art' research related to predicting X is not to be found in computer science journals, it's mainly found in economy/econometrics and marketing journals.
So in summary, is it normal or O.K to use references from non-computer science journals in a computer-science related research proposal?
