  1. Research Problem

  2. Outline • Learn how to define a research problem in CS field.

  3. How to Find Research Problems • “There were two kinds of scientists: big-bone hunters and small-bone hunters” The biological anthropologist Loren Eiseley • If Eiseley had been a programmer, he would have called this "bottom-up science." http://www.cs.jhu.edu/~jason/advice/how-to-find-research-problems.html

  4. How to Find Research Problems • Computer science includes many different kinds of research efforts. You can contribute to one of these • The smallest bone in CS • implementation of someone else's work. • Not original but useful to your education and to the field. Example : Implementation of an authentication algorithm. http://www.cs.jhu.edu/~jason/advice/how-to-find-research-problems.html

  5. How to Find Research Problems 2. A significant small bone that improves a well-known technique. • When reading papers, stay on the lookout for such bones. In particular, notice when the author may be making harmful simplifications or arbitrary choices in his/her approach. These are opportunities for you to try something different. . http://www.cs.jhu.edu/~jason/advice/how-to-find-research-problems.html

  6. How to Find Research Problems 3. (Medium Size Bone) Along the same lines, you might make a controlled comparison of two or more algorithms • Evaluating them by some objective measure of efficiency or accuracy. • Designing a clean comparison does take thought, and carrying it out is often a lot of work. • Note that quantitative studies of this sort are becoming increasingly important in some areas of CS (e.g., operating systems, machine learning, natural language, algorithms). • Example : Comparison between genetic algorithms and particle swarm optimization http://www.cs.jhu.edu/~jason/advice/how-to-find-research-problems.html

  7. How to Find Research Problems 4. Review the existing research in some area. • Note that this takes a good deal of time to do well, and is not likely to do much for your career unless a lot of people read and cite your lit review. • Writing a lit review will make you • An expert, able to talk confidently with other researchers in the area; • it will give you an idea of the shortcomings of past research; • and it may suffice for M.S.E. thesis, or the first part of a Ph.D. thesis. Example “Brain–Computer Interface Technologies in the Coming Decades” This paper focuses on using online brain–signal processing to enhance human–computer interactions; it highlights past and current BCI applications and proposes future technologies that will make significant expansion into education, entertainment, rehabilitation, and human–system performance domains. http://www.cs.jhu.edu/~jason/advice/how-to-find-research-problems.html

  8. How to Find Research Problems 5. Build a large program or device of some kind. • This gets you some name recognition • confirms your ability as a software engineer. Ex; King Abdulaziz City for Science and Technology’s SANAM 6. Identify various problems or issues as significant. • These often represent big bones in the skeleton of the field – • problems that arise often, and whose solution makes a difference. How ? • Get to know some of these problems and the work that's been done on them. • If you see how to achieve the first-ever solution, or a better solution, or a different style of solution, that's a big deal. Example : 3D Gaze estimation. (vedio) http://www.cs.jhu.edu/~jason/advice/how-to-find-research-problems.html

  9. How to Find Research Problems 7 . Big-bone Research • study important papers in your branch of computer science, flip through some conference proceedings to see what people are working on • ask: What problems (recognized or unrecognized) are obstructing progress in my field? Can I solve them? If not, can I at least formalize them? Can I prove to my colleagues that solving them would make a difference? http://www.cs.jhu.edu/~jason/advice/how-to-find-research-problems.html
