Spatial-Frequency Data Acquisition using Rotational Invariant Pattern Matching in Smart Environments
This article details the development and testing of an empirical data capture system with the ability to collect spatial-frequency statistics relating to the movement behaviour of a smart home inhabitant. This is achieved ...

User-based Collaborative Filtering: Sparsity and Performance
(IOS Press, 2010-12-14)
It is generally assumed that all users in a dataset are equally adversely affected by data sparsity and hence addressing this problem should result in improved performance. However, although all users may be members of a ...
Collaborative Filtering: The Aim of Recommender Systems and the Significance of User Ratings
This paper investigates the significance of numeric user ratings in recommender systems by considering their inclusion / exclusion in both the generation and evaluation of recommendations. When standard evaluation metrics ...
Ontology-Enabled Activity Learning and Model Evolution in Smart Homes
(Springer, Berlin, Heidelberg, 2010-10-26)
Activity modelling plays a critical role in activity recognition and assistance in smart home based assisted living. Ontology-based activity modelling is able to leverage domain knowledge and heuristics to create Activities ...
Formal Modeling Techniques for Ambient Assisted Living
In the development of systems of ambient assisted living (AAL), formalized models and analysis techniques can provide a ground that makes development amenable to a systematic approach. We consider the following formal ...
Facilitating experience reuse: towards a task_based approach
(Springer, Berlin, Heidelberg, 2010-06-22)
This paper proposes a task-based approach to facilitate experience reuse in knowledge-intensive work environments, such as the domain of Technical Support. We first present a real-world motivating scenario, product technical ...
Situation Aware Cognitive Assistance in Smart Homes
(Rinton Press, 2010-09)
Smart Homes (SH) have emerged as a realistically viable solution capable of providing technology-driven assistive living for the elderly and disabled. Nevertheless, it still remains a challenge to provide situation-aware ...
Stopping Criterion impact on Pure Random Search Optimisation for Intelligent Device Distribution
The number of intelligent environment implementations such as smart homes is set to increase dramatically within the next 40 years. This is predicted using forecasts of demographic data which indicates an expansion of the ...
Engineering Knowledge for Assistive Living
This paper introduces a knowledge based approach to assistive living in smart homes. It proposes a system architecture that makes use of knowledge in the lifecycle of assistive living. The paper describes ontology based ...
