I've noticed that depts typically go over the top student from the top school who worked with the most famous person at that school. Obviously, these people are likely to be successful. However, there are a lot of students with "unconventional" backgrounds, or that (for geographic / financial reasons) came from schools where undergraduate research is fairly bad, and so they choose to work in industry instead during the summers. I think ignoring those candidates in favour of the more conventional ones is a mistake. It also makes the research at the institution somewhat more 'conformist' - since students with unusual backgrounds might have usual ideas to contribute.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-8890204.post-28042515341693247632009-01-23T08:28:00.000-05:002009-01-23T08:28:00.000-05:00I think Michael's emphasis on success as completin...I think Michael's emphasis on success as completing a thesis is important. The last thing we (faculty) want is someone who will not complete a thesis.<BR/><BR/>In that sense "brainppower" is important. If someone is *extremely* talented in math, then they're likely to be able to complete a theory thesis even if not a great one. Also, math skills are relatively easier to measure - they are visible at an early age. In contrast motivation may only appear when the student found the right topic.<BR/><BR/>The short answer is that at the end it's very hard to predict the future, and indeed there are many current theory superstars who were not admitted to their top choice. But when you have to make a decision, you go with whatever information you have. <BR/><BR/>I'd guess that a place like Harvard can't afford to take a chance on a B student, even though such a bet will pay off handsomely once in a while. Still as i said, from past examples it seems these student will still go on to be successful at his/her second or third best choice, and the loss is only Harvard's.<BR/><BR/>Grades in certain courses, achievements such as math olympiads, all-India exam, etc.. are good indicators of math ability. In addition we take a very deep look at the recommendation letters. If a certain person has built trust over the years, by recommending the best people enthusiastically and giving clear indication of who is only second best, then we give great weight to their opinion.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-8890204.post-63518970421935532312009-01-19T18:35:00.000-05:002009-01-19T18:35:00.000-05:001) I was ACCEPTED to Harvard Comp Sciin 1980 and w...1) I was ACCEPTED to Harvard Comp Sci<BR/>in 1980 and went (it was probably called<BR/>Applied Math.

(Top 20 school; I have been on the grad admissions committee multiple times.)<BR/><BR/>> What is the typical amount of <BR/>> undergraduate research done by <BR/>> someone admitted?<BR/><BR/>As someone else pointed out, a majority of accepted applicants have some prior research experience. Note that this does <EM>not</EM> mean a published paper, or even significant progress. What it means is that you were interested enough in some topic to seek out a professor and become more knowledgeable in an area. This demonstrates enthusiasm and initiative; indicates that you will have a better chance of knowing what you want to work on when you get to graduate school; and will give you a meaningful recommendation letter that says more than "did well in my class".<BR/><BR/>> Would you ever accept someone <BR/>> with a math degree with no <BR/>> background in cs? What about <BR/>> physics? Would these be less <BR/>> advantageous or not versus an <BR/>> undergraduate cs degree?<BR/><BR/>Absolutely. Some of the best candidates come from math, and I have seen some good ones come from physics. But you have to make the case (1) why you are switching and (2) that you will be able to complete a CS course-load (which includes programming courses).Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-8890204.post-81808087691170175922009-01-17T15:49:00.000-05:002009-01-17T15:49:00.000-05:00Anon 8 (and 6):You appear to be using slightly dif...Anon 8 (and 6):<BR/><BR/>You appear to be using slightly different versions of "successful". <BR/><BR/>Generally, I believe a networking (or more generally in systems) a graduate student with reasonable technical skills, patience, and an advisor willing to find a good project, will be successful in completing their degree. There can be challenges along the way, but a minimal thesis can usually be managed, and in this sense Anon 6 is right. This doesn't mean that it's easy to become successful in the sense of, for example, turning into a good faculty candidate. For that, more significant skills -- in particular, the ability to choose good problems and come up with creative ways to solve them -- is clearly required. <BR/><BR/>In contrast, anonymous 8, for theory, patience and basic skills are just simply not generally sufficient to get through with a PhD. Your phrasing of "patience to work out the math" demonstrates a lack of understanding of what goes into a theory PhD, although I suspect you do understand and are just choosing a provocative phrase. <BR/><BR/>This issue comes up in my undergraduate theory classes all the time. Students who are used to programming complain that they can spend countless hours on a theory problem and not get anywhere. (The horror, the horror.) In systems work that is primarily programming-based, there's more nearly a linear relationship between time input and work output. Of course, there's the issue of figuring out WHAT should be programmed, but again, in systems work, if your definition of success is JUST to get out with a completed thesis, in my experience an advisor can more readily give you something to do. <BR/><BR/>So Anon 8, you're right to take Anon 6 to task, but your analogous statement for theory is, I think, way off the mark.Michael Mitzenmacherhttps://www.blogger.com/profile/02161161032642563814noreply@blogger.comtag:blogger.com,1999:blog-8890204.post-17979618988926669312009-01-17T14:41:00.000-05:002009-01-17T14:41:00.000-05:00Quoting Anon (January 15, 2009 6:09 PM):"In system...Quoting Anon (January 15, 2009 6:09 PM):<BR/><BR/>"In systems, I would imagine B with research is a much safer bet, <I>because you are almost guaranteed success given enough patience to code and test stuff.</I>"<BR/><BR/>Really?

For example, a good undergrad theory course shouldn't just be giving fill-in-the-blank proof exercises, so an A should actually tell something about how well the student does coming up with "new" ideas (new to them at least). So perhaps the grade is less telling than the particular undergrad institution they're coming from.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-8890204.post-56670213498580821342009-01-15T18:09:00.000-05:002009-01-15T18:09:00.000-05:00I think the short answer is that you never know. I...I think the short answer is that you never know. I was a straight A student, but did not do any research as an undergraduate. And, indeed, it took me a while to be successful in research. However, I was lucky MIT still accepted me and gave me an opportunity. On the other hand, I saw students who: (a) were straight A, did not do much research, and painfully failed in grad school; (b) were B students, did some (not too deep) research, were accepted only because of that, and then failed to do more serious research, because of lack of knowledge/talent; (c) were B students who succeeded greatly in research by doing it early.<BR/><BR/>So one must always make a guess. Personally, I would almost always take an A student over a B student, unless the research done by B is already serious enough to judge (i.e., appeared at a major conference, and not just some incremental junk). But this is because I'm in theory and knowledge is important. In systems, I would imagine B with research is a much safer bet, because you are almost guaranteed success given enough patience to code and test stuff.

From my experience in grad school and also now as a professor and supervisor, some of the best brainiacs fail and some ok but not so great minds go on to great accomplishments. I'd place that threshold somewhere in the upper 1-3% of the general CS population and upper 10-20% of students in an elite school.<BR/><BR/>FWIW: I was very much a type A student (straight A's, IQ in top 0.1%, started doing research in 1st year undergrad, you name it), so this defense of Type B students is not a self-serving remark.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-8890204.post-20762123452716452132009-01-15T03:08:00.000-05:002009-01-15T03:08:00.000-05:00These days among grad applicants there are fewer a...These days among grad applicants there are fewer and fewer students who haven't had the opportunity for undergraduate research. You really don't have to be one of the very top students to get involved. However, the quality of this experience varies dramatically and this variation often has little to do with the student and much more to do with the properties of the particular faculty they've happened to interact with. <BR/><BR/>One worry about all this undergraduate research is that students will tend to keep doing precisely what they've been successful at which will make them much narrower graduate students; they have specialized based on much less information than they would have had access to in grad school.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-8890204.post-24785454296875514492009-01-15T01:10:00.000-05:002009-01-15T01:10:00.000-05:00I wonder if you could give some specifics about ho...I wonder if you could give some specifics about how you weigh the various factors. <BR/><BR/>i.
