CinC Challenge 2002 Top Scores (Final)

Computers in Cardiology Challenge 2002 Top Scores (Final)

This year's challenge scoring had an unusual twist: scores for event 1 were determined by entries in event 2, and vice versa (see the Challenge overview for details). The outcome of event 2 was determined very quickly. Rather than continuing both events until 20 September as originally announced, we collected event 2 entries until the deadline for official entrants (noon GMT on 30 April) had passed, and then determined final scores for event 1.

If you did not have a chance to submit an official entry, we encourage you to participate anyway; you can still submit classifications of the challenge dataset and receive an unofficial score. Unofficial event 1 entries are also welcome; if there is sufficient interest, we will run a second round of this challenge, using new RR interval generators and a new dataset.

Winners of each event received awards during September's Computers in Cardiology conference, where participants presented their work. The RR interval generators submitted by event 1 participants are available here.

Brief descriptions of the methods used can be viewed by following the links in the tables below to abstracts submitted by many of the entrants for presentation at Computers in Cardiology 2002.

Event 2 (classification)

Six participants received perfect scores in event 2 before the deadline for official entrants had passed. The winner was Albert C-C Yang, who not only achieved a perfect score on his first attempt, but also submitted the first entry received for event 2, only a few hours after the challenge dataset was posted.

Perfect scores of 100 were received by:
