I have made results pages for the two KDD'99
contests.  They are at

[Here is an excerpt from the announcement.  GPS]

The task for the classifier learning contest organized in conjunction
with the KDD'99 conference was to learn a predictive model (i.e. a
classifier) capable of distinguishing between legitimate and
illegitimate connections in a computer network

In total 24 entries were submitted for the contest.
There was a data quality issue with the labels of the test data,
which fortunately was discovered before results were announced publicly.
Ramesh Agarwal and Mahesh Joshi have analyzed the
data quality issue with great detail and precision, so we are confident
that the test data with corrected labels is now correct.

It is important to note that the data quality issue affected only the
labels of the test examples.  The training data was unaffected, as was
the unlabeled test data.  Therefore it was not necessary to ask
participants to submit recomputed entries.

Each entry was scored against the corrected test data by a scoring awk
script using the published cost matrix (see web page) and the true
labels of the test examples.

THE WINNING ENTRY

The winning entry was submitted by Dr. Bernhard Pfahringer of the
Austrian Research Institute for Artificial Intelligence.
