Course Structure:

Exams: There will be two exams, tentatively scheduled for Oct. 11 and Dec. 4.

Term Project: I am defining this quite loosely so that you will have enough flexibility to find something you will enjoy working on. There are suggestions for projects in some of the reference books (e.g., see book by Rabiner and Schafer). Also, the book by O'Shaugnessy and several of the references provide an extensive reference list for topics covered in each chapter. I am available to discuss any ideas you may have.

To complete the project, everyone is required to hand in a final report and give an oral presentation to the class (see the course outline for dates.) The project accounts for 30% of the time that you normally spend outside of class on this course. That would be roughly 30 hours of work on your part. This is a significant investment of time, but I feel that it can be very worthwhile. A WORD OF CAUTION: Do not wait until the day before the deadline to invest your 30 hours! To help you get an early start, you are required to hand in a paragraph describing your project by Oct. 11. In addition, a short progress report (1 page) is due Nov. 13. Plan to do something on your project each week.
