 CFP: IJCAI'97 Workshop on Abduction and Induction in AI

                           Second Call for Papers

                            IJCAI'97 Workshop on

                        {*filter*} and Induction in AI

                    Nagoya, August 23-25, 1997 (one day)

                    Submission deadline: March 10, 1997



{*filter*} and induction have been recognized as important forms of reasoning
with incomplete information that are appropriate for many problems in
Artificial Intelligence. {*filter*} is generally understood as reasoning from
effects to causes or explanations, and induction (or inductive
generalisation) as inferring general rules from specific data. In Artificial
Intelligence, a typical application of {*filter*} is diagnosis, and a typical
application of induction is learning from examples.

In spite of their importance in AI, our current understanding of the logical
inference operations underlying {*filter*} and induction is incomplete and
incoherent. For instance, both {*filter*} and induction are often perceived
as embodying a form of "reversed" deduction: together with the background
knowledge, the hypothesis should entail a given observation or set of
observations. This view is incomplete, since in many cases abductive or
inductive hypotheses do not entail the observations. It is also incoherent,
in that it does not recognise the fundamental differences between {*filter*}
and induction.

This workshop is intended to improve our understanding of the inference
operations underlying abductive and inductive reasoning, and the relation
between the two. Particular emphasis will be given to the study of these
forms of inference in the context of Artificial Intelligence.


Workshop focus

This workshop is the second of its kind, the first one being organised at
ECAI'96 in Budapest. The previous workshop brought together people from
different disciplines, and identified some of the main general issues (see
the workshop report at http://www.*-*-*.com/ :2080/ECAI96/report.html). The
aim of this second workshop is to address the issue of {*filter*} and
induction in the context of practical AI problems. The following questions
summarise the workshop's focus:

  1. What (if anything) distinguishes/characterizes each form of reasoning
     and their corresponding computational models?
  2. How can we characterize different prototypical AI tasks for which it is
     appropriate to use one of these two forms of reasoning?
  3. How can {*filter*} and Induction be integrated in the context of
     Artificial Intelligence problems? For example,
        o How do we learn abductive theories?
        o How do we use {*filter*} in machine learning problems?


How to contribute

It is the organizers' intention to provoke a genuine workshop atmosphere. In
order to achieve this we solicit position papers rather than full technical
papers. Furthermore, the presentations and discussions at the workshop will
be limited to a few key issues.

Position papers

By a position paper we mean a short paper (2-4 pages) that is specifically
written for the purposes of this workshop. It may contain a brief summary of
one's own research programme and results, but it should address at least one
general topic of the workshop and identify general issues related to or
arising from this work. Authors are encouraged to indicate general problems
that they believe need to be addressed and therefore should be amongst the
topics of discussion at the workshop. Submission of a position paper would
normally be required for participation in the workshop. The number of
participants will be limited to max. 30.

Your position paper should reach the Program Committee by March 10, 1997.
Email submissions are encouraged (postscript, HTML, ASCII, or LaTeX; for
other formats see the workshop's WWW pages). Submissions should be sent to
the following address:

        Peter Flach, IJCAI'97 workshop
        INFOLAB, Tilburg University
        POBox 90153, 5000 LE  Tilburg, the Netherlands

Submitted papers will be evaluated by the Program Committee. Authors of
accepted papers may expand these to a maximum of 8 pages. These papers as
well as a list of discussion topics arising from them will be available
on-line before the workshop.

On-line material

Additional background material will be made available through the workshop's
WWW pages at http://www.*-*-*.com/ :2080/IJCAI97/, or by anonymous FTP at Workshop notes of the ECAI'96 workshop, as
well as a workshop report, can be found at
http://www.*-*-*.com/ :2080/ECAI96/ . There is an email discussion list for
topics concerning {*filter*} and induction; contact Peter Flach if you want
to be included.

Workshop format

The workshop itself will consist of presentations and moderated discussions.
The presentations are intended to put the issues under discussion into
context. The speakers will be selected among the authors of accepted papers
by the Program Committee. In addition, there will be one or two invited
The discussions will each address one of the main topics of the workshop.
The topics for discussion will be preselected by the Program Committee
according to the submitted papers, but participants will be encouraged to
propose other topics at the workshop.

Please note that in order to participate in this workshop you have to
register for IJCAI'97!
