The smart home paradigm is a promising new trend of research aiming to propose an alternative to postpone the institutionalization of cognitively-impaired silver-aged people. These habitats are intended to provide security, guidance and direct support services to its resident. To be able to fulfill this important mission, a smart home system first has to(More)
This paper 3 addresses the problem of recognizing the behavior of a person suffering from Alzheimer's disease at early-intermediate stages. We present a keyhole plan recognition model, based on lattice theory and action description logic, which transforms the recognition problem into a classification issue. This approach allows us to formalize the plausible(More)
We propose a formal framework to keyhole plan recognition based on lattice theory and action description logic. This framework minimizes the uncertainly about the prediction of the observed agent's behaviour by dynamically generating new implicit intentions. This approach offers an effective solution to actual recognition of ADL in a smart home, in order to(More)
— Assistance to people suffering from cognitive deficiencies in a smart home raises complex issues. Plan recognition is one of them. We propose a formal framework for the recognition process based on lattice theory and action description logic. The framework minimizes the uncertainty about the prediction of the observed agent's behaviour by dynamically(More)
To face new challenges caused by society aging, several researchers have initiated the experimentation of serious games as a re-education platform to help slowing down the decline of people suffering from Alzheimer. In the last few years, academic studies have been conducted and some commercial products (Nintendo's Brain Age, Big Brain Academy, etc.) have(More)
Research on progressive dementia increased significantly in the past years due to the urgency of the aging population. Patients suffering from such dementia, for instance Alzheimer's disease, lose efficiency in cognitive spheres such as memory, planning skills, initiative and perseverance. Some researchers tried to evaluate the potential of close-to-reality(More)
Smart home technologies constitute a potential solution to allow people with Alzheimer's disease (AD) to remain in their home. These intelligent houses contain technological devices aiming to provide adapted cognitive assistance (prompts) when needed. However, a literature review of the field revealed a predominant use of verbal prompts with little(More)
A major challenge in the field of Multi-Agent Systems is to enable autonomous agents to allocate tasks efficiently. This paper extends previous work on an approach to the collective iterative task allocation problem where a group of agents endeavours to make the best allocations possible over multiple iterations of proposing, selection and learning. We(More)
