As everybody knows, research experience helps in one undergraduate's admission to a PhD program. It would be even better, if the undergraduate has a publication out of his or her research experience.
However, for a full-time undergraduate, it is quite difficult to devote too much time to research since one still has the school work to deal with. (Maintaining a high GPA is also important, isn't it?) Given the time limitation by this or other reasons, the undergraduate may face the following dilemma.
The quality of work is low, but the undergraduate has no time to improve it.
Should the undergraduate publish it to a random and low-tier conference to at least have a publication?
Should he or she just make it a technical report instead of publishing it?
In other words, during the PhD admission, how do the admission committees or professors view a low-quality conference paper? Do they take it as an advantage in the sense that most of the undergraduates have none. Or do they start suspecting the student's research potentials? Does a low-quality "1" win a "0" in this case?
FYI, the field of interest is EECS, but any generic comments are also very much appreciated!
