Data Mining Cup 2010
With the end of my studies in sight, I decided to participate in the
Data Mining Cup one last time. Without the support of
i6
but in cooperation with Patrick Doetsch, we worked for 2 weeks straight
and submitted two different solutions. Patrick ranked 6th and I ranked
4th which is quite ok, but didn't come up to our expectations.
KDD Cup 2009
In 2009 our data-mining-team participated in the KDD Cup instead of the
Data Mining Cup due to some unattractive rule changes. The task was to
predict customer behaviour based on data from the French Telecom
company Orange. My submission came in 44th among 89 qualified
participants and our team's best result came in 35th, which sounds
quite unspectacular. Limited to the small challenge and without
unscrambling the big data set (which was originally intended by the
competition's organizers) we ranked first and presented our results at
the SIGKDD 2009. Anyhow, we competed successfully - as a team of
students - with research facilities from all over the world including
IBM Research, who actually came in first.
Data Mining Cup 2008
In 2008 I joined a practical course on data mining at i6,
which mainly consisted of participating in the annual Data Mining Cup
organized by prudsys. In this competition we had to predict lottery
customer behaviour. Sadly I somehow damaged my submission and ranked
among the average. The rest of the team was more successful and
occupied rank 1 to 8 (actually 1 to 9, but the so-called jury mixed up
the submissions). The man who announced the winners was very upset when
he realized that there was no tension left after declaring ranks 10 and
9. However, we had a good time during the competition and some amusing
days in Leipzig.
InformatiCup 2007
Some of my co-students won the InformatiCup in 2006, so in 2007 I
decided to give it a try myself. We worked in a group of 3. Among
several possibilities we picked the task of developing a solver for
cross number puzzles. I did the user interface and spared no effort in
order to receive the extra price for best graphical user interface.
Sadly, we came in 7th and didn't win anything. One of us attended the
presentation of the solutions and after all reported that the winning
team had no clues we didn't have as well.
