For Registration Information: ali...@cogs.susx.ac.uk
In the last five years there has been an explosion of research on
Neural Networks and Robotics from both a self-learning and an
evolutionary perspective. Within this movement there is also a growing
interest in natural adaptive systems as a source of ideas for the
design of robots, while robots are beginning to be seen as an
effective means of evaluating theories of animal learning and
behaviour. A fascinating interchange of ideas has begun between a
number of hitherto disparate areas of research and a shared science of
adaptive autonomous agents is emerging. This two-day workshop
proposes to bring together an international group to both present
papers of their most recent research, and to discuss the direction of
this emerging field.
WORKSHOP FORMAT:
The workshop will consist of half-hour presentations with at least 15
minutes being allowed for discussion at the end of each presentation.
Short videos of mobile robot systems may be included in presentations.
Proposals for robot demonstrations are also welcome. Please contact
the workshop organisers if you are considering bringing a robot as
some local assistance can be arranged. The workshop format may change
once the number of accepted papers is known, in particular, there may
be some poster presentations.
WORKSHOP CONTRIBUTIONS:
Contributions are sought from researchers in any field with an
interest in the issues outlined above.
Areas of particular interest include the following
* Reinforcement, supervised, and imitation learning methods for
autonomous robots
* Evolutionary methods for robotics
* The development of modular architectures and reusable representations
* Computational models of animal learning with relevance to robots,
robot control systems modelled on animal behaviour
* Reviews or position papers on learning in autonomous agents
Papers will ideally emphasise real world problems, robot implementations,
or show clear relevance to the understanding of learning in both
natural and artificial systems.
Papers should not exceed 5000 words length. Please submit four hard copies
to the Workshop Chair (address below) by 30th January, 1996.
All papers will be refereed by the Workshop Committee and other
specialists. Authors of accepted papers will be notified by 24th February
Final versions of accepted papers must be submitted by 10th March, 1996.
A collated set of workshop papers will be distributed to workshop attenders.
We are currently negotiating to publish the workshop proceedings as a book.

Subject: Fuzzy ART architecture papers online
From: Matthias Blume <mab...@sdcc10.ucsd.edu>
Date: Fri, 08 Dec 1995 14:03:18 -0800
Dear Connectionists,
Two papers describing a simple and efficient architecture for Fuzzy ART and
Fuzzy ARTMAP are now available online. (Sorry, hardcopies are not available.)
- ------------------------------------------------------------------------------
Matthias Blume and Sadik C. Esener,
An efficient mapping of Fuzzy ART onto a neural architecture (5 pages),
submitted to Neural Networks.
A novel mapping of the Fuzzy ART algorithm onto a neural network architecture
is described. The architecture does not utilize bi-directional synapses,
weight transport, or weight duplication, and requires one fewer layer of
processing elements than the architecture originally proposed by Carpenter,
Grossberg, & Rosen (1991). In the new architecture, execution of the
algorithm takes constant time per input vector regardless of the relationship
between the input and existing templates, and several control signals are
eliminated. This mapping facilitates hardware implementation of Fuzzy ART and
furthermore serves as a tool for envisioning and understanding the algorithm.
Keywords: Fuzzy ART, Fuzzy ARTMAP, parallel hardware, neural architecture.

Matthias Blume and Sadik C. Esener,
Optoelectronic Fuzzy ARTMAP processor,
Optical Computing, Vol. 10, 1995 OSA Technical Digest Series
(Optical Society of America, Washington, DC, 1995), p. 213-215, March 1995.
The Fuzzy ARTMAP algorithm can perform well even with weights truncated to 4
bits during training. Furthermore, only the weights corresponding to one
processing element are updated after each training sample. Finally, it
converges rapidly and relatively uniformly with little dependence on the
particular choice of adjustable parameter values and initial state. These
characteristics are particularly advantageous for parallel optoelectronic
implementations. We map Fuzzy ARTMAP onto an architecture which satisfies the
constraints of the hardware, and suggest an implementation which is an
appropriate combination of optical and electronic technology. The proposed
mapping of the algorithm onto a neural architecture is efficient, requiring
only an input layer and one processing layer per fuzzy ART module, and
requiring neither weight transport nor multiple copies of weights. The
proposed optoelectronic system is simple, yet versatile, and relies on proven
components.
Keywords: Parallel optoelectronic hardware, Fuzzy ART, neural architecture.

Subject: CFP: AAAI-96 Workshop on Integrating Multiple Learned Models
From: IMLM Workshop (pkc) <im...@tuck.cs.fit.edu>
Date: Mon, 18 Dec 1995 16:39:40 -0500
CALL FOR PAPERS/PARTICIPATION
INTEGRATING MULTIPLE LEARNED MODELS
FOR IMPROVING AND SCALING MACHINE LEARNING ALGORITHMS
to be held in conjunction with AAAI 1996
Portland, Oregon
August 1996
Most modern machine learning research uses a single model or learning
algorithm at a time, or at most selects one model from a set of
candidate models. Recently however, there has been considerable
interest in techniques that integrate the collective predictions of a
set of models in some principled fashion. With such techniques often
the predictive accuracy and/or the training efficiency of the overall
system can be improved, since one can "mix and match" among the
relative strengths of the models being combined.
The goal of this workshop is to gather researchers actively working in
the area of integrating multiple learned models, to exchange ideas and
foster collaborations and new research directions. In particular, we
seek to bring together researchers interested in this topic from the
fields of Machine Learning, Knowledge Discovery in Databases, and
Statistics.
Any aspect of integrating multiple models is appropriate for the
workshop. However we intend the focus of the workshop to be improving
prediction accuracies, and improving training performance in the
context of large training databases.
More precisely, submissions are sought in, but not limited to, the
following topics:
1) Techniques that generate and/or integrate multiple learned
models. In particular, techniques that do so by:
* using different training data distributions
(in particular by training over different partitions
of the data)
* using different output classification schemes
(for example using output codes)
* using different hyperparameters or training heuristics
(primarily as a tool for generating multiple models)
2) Systems and architectures to implement such strategies. In particular:
* parallel and distributed multiple learning systems
* multi-agent learning over inherently distributed data
A paper need not be submitted to participate in the workshop, but
space may be limited so contact the organizers as early as possible if
you wish to participate.
The workshop format is planned to encompass a full day of half hour
presentations with discussion periods, ending with a brief period for
summary and discussion of future activities. Notes or proceedings for
the workshop may be provided, depending on the submissions received.
Submission requirements:
i) A short paper of not more than 2000 words detailing recent research
results must be received by March 18, 1996.
ii) The paper should include an abstract of not more than 150 words,
and a list of keywords. Please include the name(s), email
address(es), address(es), and phone number(s) of the author(s) on the
first page. The first author will be the primary contact unless
otherwise stated.
iii) Electronic submissions in postscript or ASCII via email are
preferred. Three printed copies (preferrably double-sided) of your
submission are also accepted.
iv) Please also send the title, name(s) and email address(es) of the
author(s), abstract, and keywords in ASCII via email.

Cellular automata can be thought of as a
restricted kind of neural net, in which the
cells take on only a finite set of values,
and connections are local and regular.
This is set of interactive web pages designed to help
you learn about CA, and the use of the lambda
parameter to find critical regions in the space of
CA.
