This course is loosely based on two themes: connecting theory and practice, and how to deal with really big data (especially over networks). The topics change from offering to offering, and the below is subject to change. The course will consist of multiple independent units, covering the major themes of data sketches and streaming algorithms, information theory/coding algorithms, compression, and hashing-based algorithms generally.
Although the course will emphasize theoretical foundations, the course is meant to show the synthesis of theory and practice; we will often read pairs of papers, one from the "theory community" and one from the "systems community", on the same theme. The course is also meant to promote skills required of graduate students, such as criticial and creative reading and analysis of papers, and research.
The main work of the course will consist of the following: reading and analyzing a number of current and classic research papers; homework problems based on the material; participating in a mock program committee; and undertaking a final research project. (I have been told the workload of the class is reasonable but non-trivial. If you were looking for a graduate class with no work requirements, please look elsewhere.)
During the semester, you will frequently be reading two research papers to prepare for each class. This is more work than it sounds like! You must come to class prepared consistently; if your schedule will not permit that, you should not take the class.
Given the current non-physical nature of classes, we will be experimenting with different formats this year. There will be less emphasis on lectures and homework, and more empahsis on other activities, most notably the final project. The intention is to make recorded lectures from a previous year available.
As an example of how to deal with this format change, I am hoping to arrange several online "interviews" with colleagues who at the interface of theory and practice, to discuss how they see the connections between them and how they have worked to bring the areas together. I am hoping they will offer perspective on the benefits and challenges of this type of research. This may replace more in-class lecture discussion.
Another variation of format for the class is that we will run a "mock program committee". I will choose papers from the arxiv and from recent conferences thematically related to the course, and the class will act as a program committee to choose the best ones. This will give you an idea of how program committees work (or don't), and let you see some more up-to-date research, as class reading will be more focused on "classics". It seems a useful for exercise gaining an understanding how program committees function, which seems helpful to graduate students.
Finally, a major component of the class will be a final project, which you will work on throughout the entire course. The hope is that this project may form the foundation of either a research paper or, for undergraduates, a senior thesis. (In previous years some small number of projects do continue with additional work to become research papers. Expectations, however, are realistic; research is exploration, and this project is understood to be the beginning, not necessarily the end, of such an exploration.) Although you will need to obtain approval for your project choice, the topic of the final project will primarily be up to you. This project can either be theoretical or implementation based in nature. Generally people work in pairs for the final project, but you can work alone or, with permission, a group of three or larger. For graduate students, your project can be related to your main line of research; it should not, however, be something you were already working on.
Students should have taken at least CS 124 or its equivalent. Students should be able to program in a standard programming language, at the level to independently produce working simulations of various processes. Knowledge of probability will be extremely helpful; if your probability background is weak you should expect to refresh your probability skills on your own. Generally, mathematics will be fundamental to the course, so you should expect to spend time learning some additional mathematics on your own if necessary. Similarly, some prior knowledge of networks and network issues will be very helpful. For students wishing to review important aspects of probability, there are many books available. Sheldon Ross has written several excellent introductory books which should be available in the library. My personal favorite is "Introduction to Probability Models." A more advanced book for those with more background is "Elements of Information Theory" by Cover and Thomas. Another good book is "Information Theory, Inference, and Learning Algorithms" by David Mackay, which has the benefit of being online: This link should work. Of course, my completely biased opinion is that the best book for a computer scientist to buy is by Mitzenmacher and Upfal, "Randomized Algorithms and Probabilistic Analysis." I'd recommend students with less background in probability get one (or more) of these books as a reference.
Your performance will be measured in five ways. (The percentage contributions to your grade given below are approximate and subject to change.)
Summaries are to be approximately 250-350 words (about 1 page). Longer is not better. Again, for summaries this year, we will be doing something different than previous years -- we will be putting them in a discussion board, and you will be expected to read some other summaries and use them as a guide to understanding the papers. These will serve as a basis for in-class discussion, which I expect to be done more in zoom subgroups among students than in a lecture-style format since we will not be physically together in lectures.
All assignments will be due at the beginning of class on the appropriate day. Late assignments are not acceptable without the prior consent of the instructor. Consent will generally be given for suitable reasons. Being busy in other classes is generally not a suitable reason.
If you collaborate with other students in the course in the planning and design of solutions to homework problems, then you should give their names on your homework papers.
Under no circumstances may you use solution sets to problems that may have been distributed by the course in past years, or the homework papers of students who have taken the course past years. Nor should you look up solution sets from other similar courses.
Violation of these rules may be grounds for giving no credit for a homework paper and also for serious disciplinary action.
