DUAL (cognitive architecture)
Encyclopedia
DUAL is a general cognitive architecture integrating the connectionist and symbol
ic approaches at the micro level. DUAL is based on decentralized representation and emergent computation
. It was inspired by the Society of Mind
idea proposed by Marvin Minsky
but departs from the initial proposal in many ways. Computations in DUAL emerge from the interaction of many micro-agents each of which is hybrid symbolic/connectionist device. The agents exchange messages and activation via links that can be learnt and modified, they form coalitions which collectively represent concepts, episodes, and facts.
Several models have been developed on the basis of DUAL. These include: AMBR (a model of analogy-making and memory), JUDGEMAP (a model of judgment), PEAN (a model of perception), etc.
DUAL is developed by a team at the New Bulgarian University
led by Boicho Kokinov

Symbol
A symbol is something which represents an idea, a physical entity or a process but is distinct from it. The purpose of a symbol is to communicate meaning. For example, a red octagon may be a symbol for "STOP". On a map, a picture of a tent might represent a campsite. Numerals are symbols for...

Emergence
In philosophy, systems theory, science, and art, emergence is the way complex systems and patterns arise out of a multiplicity of relatively simple interactions. Emergence is central to the theories of integrative levels and of complex systems....
