The purpose of data mining is to explore, find and hence analyze relevant data from a massive data source using various technical means. This paper introduces the development of data mining to date, its functions, tasks and algorithms, as well as the process of data mining. The application and problems of data mining are also presented and finally the potential future development of data mining technology...
Facial expression recognition is an interesting research topic. Considerable methods have been proposed in order to achieve high accuracy in facial expression recognition, however, only a few of these methods have considered factors like memory consumption and computational complexity. In this paper, we focus on smile detection which belongs to facial expression recognition. Compare with the proposed...
