ACM KDD CUP

There were five questions at the KDD Cup 2000. The results for Question 2 have been revised. When we calculated the results at Purdue, we had a subtle bug. The bug was uncovered thanks to Yoshinori Yaginuma who calculated his own score using the posted test data. We have corrected for this bug and have posted the new results for Question 2 (11/20/00).
