Suggested Term Projects CSE 666, Fall 2014
Guidelines • The described projects are suggestions; if you have desire, skills or idea to explore alternative topics, you are free to do so. • Finalize the project selection by October 16; have a 1-2 slide (2-3 minutes) presentation describing the project on that day. • Project reporting: • Final goal: estimate performance of proposed method or present a working demo of the system • Presentation: 20 minute on one of four days of classes(Nov. 20, 25, Dec. 2, 4). Presentation should include some topic background (previous works), description of the approach, preliminary results. • Final report : Dec. 16 ? – research style paper with results (background, previous work, detailed approach description, results, bibliography). • Working in groups: you can do so for large projects, but the work should be clearly split and separate reports from each person will have to be submitted. • Using existing projects, libraries, etc. You have to reference all such uses; the project should contain significant amount of your original work.
