Workshop Description:
---------------------

Overview:

Recent years brought increased interest in applying machine learning
techniques to difficult "real-world" problems, many of which are
characterized by imbalanced learning data, where at least one class is
under-represented relative to others. Examples include (but are not
limited to): fraud/intrusion detection, risk management, medical
diagnosis/monitoring, bioinformatics, text categorization and
personalization of information. The problem of imbalanced data is often
associated with asymmetric costs of misclassifying elements of different
classes. Additionally the distribution of the test data may differ from
that of the learning sample and the true misclassification costs may be
unknown at learning time.

The AAAI-2000 Workshop on "Learning from Imbalanced Data Sets" provided
the first venue where this important problem was explicitly addressed and
has been received with much interest. The related ICML-2000 Workshop on
"Cost-Sensitive Learning"  provided another venue for addressing the
problem of asymmetric costs of different classes and features.  Although
much awareness of the issues related to data imbalance has been raised,
many of the key problems still remain open and are in fact encountered
more often, especially when applied to massive datasets. We believe that
it would be of value to the machine learning community to not only examine
the progress achieved in this area over the last three years but also
discuss the current school of thought on research in learning from
imbalanced datasets. Based on our understanding of class imbalance problem,
the following topics of discussion are proposed (but not limited to):

* sampling (under-, over-, progressive, active)
* post-processing of learned models
* accounting for class imbalance via inductive bias
* one-sided learning
* handling uncertainty of target distribution and misclassification costs
* handling varying amounts (class dependent) of label noise


Proposed Format:

The workshop will open with an invited talk by Foster Provost that will
introduce and overview the topic. Presentations will then be organized
into several sessions corresponding roughly to the to the categories
identified above. The workshop will conclude with a discussion during
which a distinguished guest will comment on the presentations of the day,
and open the floor for general discussion.


Proposed Length:

One Day during which each panel will be allocated 1 to 2 hours, depending
on the number of contributions and the expected length of the discussion
session.


Workshop Notes:

The accepted papers will be available electronically from the workhop
website, and also as printed workshop notes to the attendees.


Submissions:

Authors are invited to submit papers on the topics outlined above or
on other related issues. Submissions should not exceed 8 pages, and
should be in line with the ICML style sheet.  Electronic submissions,
in PDF format, are prefered and should be sent to:

        Nitesh Chawla at [e-mail]

If electronic submissions are inconvenient, please send four hard copies
of your submission to:
