Automated Micro-Array Classification Challenge


Wenjia Wang and Gavin Cawley


The diagnosis of cancer on the basis of gene expression profiles is well established, so much so that micro-array classification has become one of the classic applications of machine learning in computational biology.  The field has now reached the stage where a large scale evaluation exercise is warranted to determine the advantages and disadvantages of competing approaches.  We have therefore organized a challenge for ICMLA'08, the aim of which is to determine the best fully automated approach to micro-array classification.  An unusual feature of the competition is that instead of submitting predictions on test cases, the competitors submit a MATLAB implementation of their algorithm (R and Java interfaces are also in development), which is then tested off-line by the challenge organizers.  This will test the true operational value of the method, in the hands of an end user who is not necessarily an expert in a given technique.  The winner of the challenge will receive a free registration to ICMLA'08.


Further details and background information regarding the competition are available from the challenge website, If you have any questions, please feel free to contact the challenge organizers (


The results of the challenge will be presented at a special session at ICMLA'08.  Competitors are encouraged to participate in the special session and are invited to submit a technical paper describing their technique. Submissions should be made electronically in PDF format using the central ICMLA'08 website.  The deadline for submissions is June 15, 2008   July 15, 2008.  All accepted papers must be presented by one of the authors in order to be published in the conference proceeding.
