Agenda and Announcements • Machine Learning assignment will go out on Thursday. • Tutorial in class on tool for homework • Today: – Tournament – Application in machine learning – Midterm results – HW 1 results 2

Tournament Structure • 1 st round randomly seeded – Who plays who – Starter rank random • After each game, players who have won same number of games play against each other – 5 -6 rounds • • Prediction of length of time: 100 min per round, 10 hours Will post a web site that tracks Lab date not yet confirmed Extra credit • • 1. 5 points for passing entrance test 1. 5 points for top 50% 1. 5 points for top 5 1. 5 points for top 1 3

KDD Cup • • Knowledge Dissemination and Discovery 2003 – Predicting interest in journal papers –SVMs a winner 2002 – Bioinformatics - e. g. , given a set of bioinformatics papers and a list of genes mentioned in each paper, determine for each gene whether the paper has full experimental evidence 2001 – Bioinformatics – prediction of biomolecular activity for drug design; prediction of gene/protein function and localization 2000 – Predicting user activity in online product web site (legwear) 1999 – Network intrusion detection. Given 5 million connection records, predict normal vs. attack (denial of service, remote unauthorized access, local unauthorized access, probing) 1998 – Predict who will give how much to a specific charity based on a variety of demographics 1997 - Two of the 3 winners used Naïve Bayes classifiers 4
