A type-2 fuzzy embedded agent to realise ambient intelligence in ubiquitous computing environments

In this paper, we present a novel approach for realising the vision of ambient intelligence in Ubiquitous Computing Environments (UCEs). This approach is based on embedding intelligent agents in UCEs. These agents are based on type-2 fuzzy systems which are able to handle the different sources uncertainty and imprecision in UCEs to give a good response. We have developed a novel system for learning and adapting the type-2 fuzzy agents so that they can realise the vision of ambient intelligence by providing a seamless, unobtrusive, adaptive and responsive intelligence in the environment that supports the activities of the user. The user’s behaviours and preferences for controlling the UCE are learnt online in a non intrusive and life long learning mode so as to control the UCE on the user’s behalf. We have performed unique experiments in which the type-2 intelligent agent has learnt and adapted online to the user’s behaviour during a stay of five days in the intelligent Dormitory (iDorm) which is a real UCE test bed. We will show how our type-2 agents will realise the vision of ambient intelligence and deal with the uncertainty and imprecision present in UCEs to give a very good response that outperforms the type-1 fuzzy agents while generating a smaller number of rules.
