Automatic Construction of Finite Automata for Online Recognition of User Activities in Smart Environments
H. Karamath Ali · IOSR Journal of Engineering · 2013
Recognizing user activities unobtrusively is very important for offering context aware services in pervasive computing environments.Because of their ability to classify given inputs in a simple and efficient manner, Finite State Machine(FSM)s have good potential to be used for recognizing user activities.However, the manual construction of FSMs in the existing methods require a domain expert with enough insight to dissect the activity of interest into an FSM.Obviously, this requirement imposes huge burden on the experts when constructing FSMs for recognizing activities that are not so repetitive in nature.In this paper, we propose a method for automatic construction of an FSM that can be used to recognize user activities in real time.The proposed method gives promising results when tested with publicly available smart home datasets.
