Finding original research ideas/topics as an undergraduate student
To develop something that is both (1) new and (2) meaningful, you'd have to start by reading a lot of published research to find out what is already out there. After reading widely, you'd start to get a sense for what the trends are in the field, and possibly start to see some gaps that point to open research problems. You'd also start to see what you'd be expected to do and say in a similar paper, i.e. the standards and conventions in the field, what kind of contributions a new model is expected to make, etc.

This is very difficult and time consuming for someone working alone without a lot of experience in the field. (It would definitely take more than a month!) The best "shortcut" is to find one or more advisors (perhaps the advisor from your independent study?) who can help point you in a promising direction, and give you feedback on your work.
