DUAL is a general cognitive architecture integrating the connectionist and symbolic approaches at the micro level.
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.
DUAL is developed by a team at the New Bulgarian University led by Boicho Kokinov.
The third version is co-authored by Georgi Petkov and Ivan Vankov.
