Error-Correcting Output Codes:
A General Method for Improving
Multiclass Inductive Learning Programs

Multiclass learning problems involve finding a definition for an
unknown function f(x) whose range is a discrete set containing k>2
values (i.e., k ``classes''). The definition is acquired by studying
large collections of training examples of the form <x_i, f(x_i)>.
Existing approaches to this problem include (a) direct application of
multiclass algorithms such as the decision-tree algorithms ID3 and
CART, (b) application of binary concept learning algorithms to learn
individual binary functions for each of the k classes, and (c)
application of binary concept learning algorithms with distributed
output codes such as those employed by Sejnowski and Rosenberg in the
NETtalk system. This paper compares these three approaches to a new
technique in which BCH error-correcting codes are employed as a
distributed output representation. We show that these
error-correcting output representations improve the performance of ID3
on the NETtalk task and of backpropagation on an isolated-letter
speech-recognition task. These results demonstrate that
error-correcting output codes provide a general-purpose method for
improving the performance of inductive learning programs on multiclass
problems.
This paper will appear in AAAI-91.

SYMPOSIUM ON
ARTIFICIAL INTELLIGENCE, REASONING AND CREATIVITY
20-23 AUGUST 1991
immediately preceding the
International Joint Conference on Artificial Intelligence
(IJCAI'91)
organised by
GRIFFITH UNIVERSITY, BRISBANE, AUSTRALIA
to be held at
LAMINGTON NATIONAL PARK, QUEENSLAND, AUSTRALIA
AIM
Creativity is one of the least understood aspects of intelligence. It is
commonly regarded as 'intuitive' and not susceptible to rational enquiry.
However, there is now considerable work in artificial intelligence and
cognitive science which addresses creativity. This symposium will provide a
forum for exploring and discussing these ideas, and for suggesting directions
for future research. It aims to attract practitioners of both 'cognitive'
and 'technological' artificial intelligence.
KEYNOTE SPEAKER - PROFESSOR MARGARET BODEN
Margaret Boden, in her talk on `Creativity and Computers', will discuss
how computational concepts drawn from artificial intelligence can explore
creativity. Computers can sometimes do apparently creative things;
more to the point, they can suggest how we manage to do so. Computational
ideas are therefore helping us to understand how human originality is
possible.
Margaret Boden is Professor of Philosophy and Psychology, and Founding
Dean of the School of Cognitive Sciences, at the University of Sussex, UK. Her
recent publications include `Artificial Intelligence and Natural Man' (1987),
`Artificial Intelligence in Psychology' (1989) and `The Creative Mind: Myths
and Mechanisms (1991).
INVITED SPEAKERS include
Ernest Edmonds, Loughborough University, UK
John Gero, University of Sydney, Australia
Graham Priest, University of Queensland, Australia
Roger Wales, University of Melbourne, Australia
TOPICS FOR PRESENTATION AND DISCUSSION
The symposium calls for extended abstracts of 750-1,000 words. The following
are suggested areas only:
- Models of creativity
- Modelling creative processes
- Creative reasoning, e.g theory generation in science
- Analogical reasoning
- Case-based reasoning
- Nonmonotonic reasoning
- Thought experiments
Both connectionist and traditional symbolic approaches are welcome.
All abstracts will be refereed. Accepted papers will be subjected to a
further refereeing process for publication by Kluwer Academic Press.
The symposium will be structured to provide adequate time for both
presentation and discussion.
SUBMISSION
Three copies of extended abstracts are required by 31 May 1991.
Abstracts may be submitted electronically as LaTeX or plain ASCII files via
email but hard copies must also be submitted. Two hard copies of final
versions of accepted papers, and an electronic version on Macintosh
disk or via email are required at the time of registration on 20 August
1991. Authors of accepted papers will be expected to sign a copyright
release form to allow publication of the proceedings. At least one
author of each paper is expected to present the paper at the symposium.
PREPRINTS AND PROCEEDINGS
Accepted extended abstracts will be printed in the form of Preprints
and be available for distribution at the time of registration.
Full papers will be published subsequently by Kluwer Academic Press.
LOCATION
The symposium is being held at O'Reillys Lodge in Lamington National Park,
Queensland - a rainforest 120 km south of Brisbane.
FACILITIES
O'Reillys is a mountain resort of modern units. The seminar facilities are
highly professional, including lecture theatre, audiovisual equipment and
library.
