The results presented in this paper show that the start-time/
duration is the most effective way of representing a large
sensor data set. This will also help with the classification of
the activities to identify the abnormal behaviour. Furthermore,
we have investigated different recurrent neural network
technique to predict the future activities. The results
presented in this paper show that ESN is a very promising
approach for binary datasets collected from smart environments.
Datasets investigated here are based on a single
inhabitant environment equipped with appropriate motion
and door contact sensors
