The aim of this 5-days workshop with 3 days of oral presentations is to bring together researchers interested in probabilistic graphical models (PGMs) and to provide a forum for discussion of the latest research developments in this field. To promote debate among the participants of the workshop, the number of accepted papers will be limited to 30-40, and there will be no parallel sessions. As we will restrict the number of participants to not more than 60, participation is by invitation only. One or two days during the workshop will be devoted to collaborative research, for which purpose the Lorentz Centre offers special facilities (see below).

 We welcome theoretical and applied results related to the following topics:


Abstract registration:

Authors, who have the intention to submit a paper to PGM'04, should indicate so by filling in the "abstract registration" form. Abstract registration must be done by 28th May, 2004. The authors should fill in the title of the paper, the author correspondence information (name, address, phone/fax number, and e-mail address), up to 5 keywords and a short summary (up to 200 words). Each submission will be assigned an  identification number. Please use it on all correspondence with the programme committee.

Paper submission:

All papers need to be uploaded at the upload site. Please note: to upload your paper you need the identification number received earlier plus your e-mail address. The paper should be submitted not later than 1st June, 2004. Papers submitted later than this will not be reviewed. Papers must be in PDF or PS format and the maximum length is 8 pages, printed single-sided. Additional instructions about the paper format are to be found in the sample paper. The program committee will make every attempt to print out your paper successfully, but cannot take responsibility if they cannot. Authors are encouraged to submit papers 48 hours before the submission deadline so that unprinting formats can be detected and corrected by the submission deadline. If for some reason an author is not able to submit electronically, please contact Peter Lucas ( concerning hard-copy submission.


Proceedings including all the accepted papers will be available at the workshop; in addition, on-line electronic proceedings will be available on this web site. Authors of the best papers will be asked to submit an enhanced and extended version of their paper to a special issue of a top-quality journal.  


The official language of the workshop will be English.
