An Unsupervised User Behavior Prediction Algorithm Based on Machine Learning and Neural Network For Smart Home.

The user operates the smart home devices year in year out, have produced mass operation data, but these data do not be utilized well in past. Nowadays, these data can be used to predict user's behavior custom with the development of big data and machine learning technologies, and then the prediction results can be employed to enhance the intelligence of a smart home system. In view of this, this paper proposes a novel unsupervised user behavior prediction (UUBP) algorithm, which employs an artificial neural network and proposes a forgetting factor to overcome the shortcomings of the previous prediction algorithm. This algorithm has a high-level of autonomous and self-organizing learning ability while does not require too much human intervention. Furthermore, the algorithm can better avoid the influence of user's infrequent and out-of-date operation records, because of the forgetting factor. Finally, the use of real end user's operation records to demonstrate that UUBP algorithm has a better level of performance than other algorithms from effectiveness.
