Discovering Temporal Features and Relations of Activity Patterns
An important problem that arises during the data mining process in many new emerging application domains is mining data with temporal dependencies. One such application domain is activity discovery and recognition. Activity discovery and recognition is used in many real world systems, such as assisted living and security systems, and it has been vastly studied in recent years. However, the temporal features and relations which provide useful insights for activity models have not been exploited to their full potential by mining algorithms. In this paper, we propose a temporal model for discovering temporal features and relations of activity patterns from sensor data. Our algorithm is able to discover features and relations, such as the order of the activities, their usual start times and durations by using rule mining and clustering techniques. The algorithm has been validated using 4 months of data collected in a smart home. Keyword--Temporal Association Rules, Temporal Features, Tempo...
