Make sure you clearly specify the class of tasks Y to which your thesis applies. Besides being a proposition, a thesis has to have another property: A defense presents evidence for a thesis.

What kind of evidence is apprpropriate depends on what kind of thesis is being defended. One defense for this kind of claim is an analysis of the complexity, or completeness, or whatever, of the theoretical algorithm.

In computer science, the more common defense is based on empirical results from running an experiment. A good defense here means more than one example, and answers to questions such as the following. What are the capabilities and limits of your experiment?

How often do the things that your experiment does come up in the real world? What's involved in extending it? If it's easy to extend, why haven't you? If your example is a piece of a larger system, how realistic are your assumptions about input and output?

The same kind of defense applies here as in the previous case, but now serious comparisons with previous systems are required. Can your result do the same examples the previous results did, or can you make them do yours? Can you prove they couldn't do your examples? If you claim to be more efficient, what are you measuring? This is usually defended by a logical argument. It is usually very tough to do, even if the argument doesn't have to be formalized.

Many students make the mistake of picking this kind of thesis to defend. It requires serious experimental evidence to defend, unless your real thesis is of the previous form, i. Selected excerpts from protocols and surveys of your officemates are not psychological evidence, no matter how much they might have inspired your work. This is a reasonable thesis if process X is a serious contender. The defense would be an analysis of the limits of process X, i.

Defending a real thesis is hard. If you think you have a lot of theses, you probably just have a bunch of undefended claims. One good thesis, or two so-so theses, with adequate description and defense, is more than enough to fill up a dissertation.

If you're bright, educated, and have worked hard on a topic for more than a year, you must have learned something no one else knew before. Once students submit their theses papers to the thesis committee, they will be assigned a date to defend their work.

Rather, the thesis defense is designed so that faculty members can ask questions and make sure that students actually understand their field and focus area. Defending a thesis largely serves as a formality because the paper will already have been evaluated. During a defense, a student will be asked questions by members of the thesis committee. Questions are usually open-ended and require that the student think critically about his or her work.

A defense might take only 20 minutes, or it might take an hour or more depending on the goal of the committee and the requirements of the program. Schools want graduate candidates to be as prepared as possible when attending a defense, which means that neither the date nor faculty committee will be a surprise to the student.

The committee wants to see how well you know your subject and your research. Nerves may get the better of you as you face unknown questions, but as with a job interview, practicing ahead of time will lead to a successful defense.

Instead, a proper thesis defense gives you and your faculty advisers the chance to discuss your topic and research in greater detail.
