 Connectionist-symbolic Integration:
 From Unified to Hybrid Approaches
 Montreal, Canada
 August 19-20, 1995

There has been a considerable amount of research in integrating
connectionist and symbolic processing. While such an approach has
clear advantages, it also encounters serious difficulties and
challenges. Therefore, various models and ideas have been proposed to
address various problems and aspects in this integration. There is a
growing interest from many segments of the AI community, ranging from
expert systems, to cognitive modeling, to logical reasoning.

Two major trends can be identified in the state of the art: these are
the unified, or purely connectionist, and the hybrid approaches to integration.
Whereas the purely connectionist ("connectionist-to-the-top") approach
claims that complex symbol processing functionalities can be achieved
via neural networks alone, the hybrid approach is premised on the
complementarity of the two paradigms and aims at their synergistic
combination in systems comprising both neural and symbolic components.
In fact, these trends can be viewed as two ends of an entire spectrum.

Up till now, overall, there is still relatively little work in
comparing and combining these fairly isolated efforts. This workshop
will provide a forum for discussions and exchanges of ideas in this
area, to foster cooperative work. The workshop will tackle important
issues in integrating connectionist and symbolic processing.
