DUAL is a general
cognitive architecture integrating the
connectionist and
symbol
A symbol is a mark, Sign (semiotics), sign, or word that indicates, signifies, or is understood as representing an idea, physical object, object, or wikt:relationship, relationship. Symbols allow people to go beyond what is known or seen by cr ...
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 a hybrid symbolic/connectionist device. The agents exchange messages and activation via links that can be learned 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. The second version was co-authored by Alexander Petrov. The third version is co-authored by Georgi Petkov and Ivan Vankov.
