Fall 2004

• This is the current list of the suggested papers, along with the names of people willing to lead the discussion on each one.

• Please select one by sending an email to adeli at umiacs.umd.edu with your choice.

• A first-asked first-served basis will be used to solve any conflicts. In other words, if two people want to lead the discussion on the same paper, the one that has asked for it first will get it.

• If two people are scheduled to lead the discussion on the same day, then they have to choose the same paper (only one should send email).

• Note that a lot of these papers are the draft versions of papers accepted to upcoming conferences. Hopefully, we will be able to have the final versions before the discussion.
