CALL FOR PAPERS
International Symposium on Integrating Knowledge and Neural Heuristics
(ISIKNH'94)
Sponsored by University of Florida, and AAAI,
in cooperation with IEEE Neural Network Council, INNS-SIG, and FLAIRS.
Time: May 9-10 1994; Place: Pensacola Beach, Florida, USA.
A large amount of research has been directed toward integrating neural
and symbolic methods in recent years. Especially, the integration of
knowledge-based principles and neural heuristics holds great promise in
solving complicated real-world problems. This symposium will provide a
forum for discussions and exchanges of ideas in this area. The objective
of this symposium is to bring together researchers from a variety of
fields who are interested in applying neural network techniques to
augmenting existing knowledge or proceeding the other way around, and
especially, who have demonstrated that this combined approach outperforms
either approach alone. We welcome views of this problem from areas such
as constraint-(knowledge-) based learning and reasoning, connectionist
symbol processing, hybrid intelligent systems, fuzzy neural networks,
multi-strategic learning, and cognitive science.
Examples of specific research include but are not limited to:
1. How do we build a neural network based on {\em a priori}
knowledge (i.e., a knowledge-based neural network)?
2. How do neural heuristics improve the current model
for a particular problem (e.g., classification, planning,
signal processing, and control)?
3. How does knowledge in conjunction with neural heuristics
contribute to machine learning?
4. What is the emergent behavior of a hybrid system?
5. What are the fundamental issues behind the combined approach?
Program activities include keynote speeches, paper presentation,
panel discussions, and tutorials.

Scholarships are offered to assist students in attending the
symposium. Students who wish to apply for a scholarship should send
their resumes and a statement of how their researches are related
to the symposium.

Program:
========
In any physical computational system, processing resources are
limited, which inevitably leads to bottlenecks in the processing of
sensory information. Nowhere is this more evident than in the primate
visual system, where the massive amount of information provided by the
optic nerve far exceeds what the brain is capable of fully processing
and assimilating into conscious experience. Visual attention thus
serves as a mechanism for selecting certain portions of the input to
be processed preferentially, shifting the processing focus from one
location to another in a serial fashion. The study of visual
attention is integral to our understanding of higher visual function,
and it may also be of practical benefit to machine vision as well.
What we know of visual attention has been learned from a combination
of psychophysical, neurophysiological, and computational approaches.
Psychophysical studies have revealed the behavioral consequences of
visual attention by measuring either a speed-up in observer's reaction
time or an improvement in discrimination performance when the observer
is attending to a task. Neurophysiological studies, on the other hand,
have attempted to reveal the neural mechanisms and brain areas
involved in attention by measuring the modulation in single cell
firing rate or in the activity in a part of the brain as a function of
the attentional state of the subject. A number of computational
models based on these studies have been proposed to address the
question of how attention eases the computational burdens faced by the
brain in pattern recognition or other visual tasks, and how attention
is controlled and expressed at the neuronal level.
The goal of this workshop will be to bring together experts from each
of these fields to discuss the latest advances in their approaches to
studying visual attention. Half the available time has been reserved
for informal presentations and the other half for discussion.

Program:
========
The objective of the workshop is to provide a discussion
platform for researchers interested in software and
modelling aspects of neural computing. The workshop should
be of considerable interest to computer scientists and
engineers as well as biologists and cognitive scientists.
The introduction of specialized hardware platforms for
connectionist modelling ("connectionist supercomputer") has
created a number of research issues which should be
addressed. Some of these issues are controversial (incl. the
need for such specialized architectures): the efficient
implementation of incremental learning techniques, the need
for the dynamic reconfiguration of networks at runtime and
possible programming environments for these machines.
The following topics should be addressed:
- - the efficient simulation of homogenuous network
architectures; mapping of homogenous network architectures
to parallel machines
- - randomness and sparse coding; the efficient simulation of
sparse networks on sequential and parallel machines. Sparse
activity and communication in parallel architectures
- - arbitrary interconnection schemes and their mapping to
parallel architectures
- - dynamic reconfiguration: the modification of network
structures and activation functions at runtime. Possible
trade-offs between the efficient simulation of fixed-sized
networks and constructive (incremental) learning algorithms
- - software tools and environments for neural network
modelling, in particular for parallel architectures
- - connectionist supercomputer (such as CNAPS, Synapse and
CNS-1) hardware and programming issues associated with
connectionist supercomputer
- - biologically realistic modelling on parallel machines, the
simulation of synaptogenesis, spike trains etc.
- - realistic simulation of the brain integrating over a
number of scales of complexity, from the detailed simulation
of neurons to high level abstractions
The following is a preliminary schedule, we expect to have two more slots
for brief presentations and invite abstracts for short talks (about 10-15min).

_____________________________ cut here _________________________
The purpose of this one-day workshop is to bring together neural
network practitioners, computer scientists and mathematicians
interested in `stability' and `observability' of neural networks of
various types (discrete/continuous time and/or activations).
These two properties concern the relationship between defining
parameters (weights, transfer functions, and training sets) and the
behavior of neural networks from the point of view of an outside
observer. This behavior is affected by noise, rounding, bounded
precision, sensitivity to initial conditions, etc. Roughly
speaking, *stability* (e.g. asymptotic, Lyapunov, structural)
refers to the ability of a network (or a family of networks) to
generate trajectories/orbits that remain reasonably close (resp.,
in structure, e.g. topological conjugacy) to the original
under small perturbations of the input/initial conditions (or the
defining parameters of the network). Of course, neural networks are
well-known for their graceful degradation, but this is less clear
an issue with bounded precision, continuous time with local
interaction governed by differential equations, and learning
algorithms.
Second, the issue of *observability*, roughly speaking, concerns
the problem of error control under iteration of recurrent nets. In
dynamical systems observability is studied in terms of
shadowing. But observability can also be construed other ways,
e.g. as our ability to identify a network by observing the abstract
i/o function that it realizes (which, at some level, reduces to
essential uniqueness of an irreducible network implementing the i/o
function).
Speakers will present their views in short(< 20 min.) talks. A
panel discussion coordinated by the cochairs will discuss known
results, and identify fundamental problems and questions of
interest for further research.
