The diversity of quality-of-service (QoS) requirements of Internet applications motivates various QoS routing algorithms that take different QoSmetrics into consideration. Routing algebra has been proposed as a framework to study the fundamental properties of QoS routing algorithms, such as their optimality and loopfreeness. However, for multipath QoS routing, little has been done in these aspects...
Rough set theory is emerging as a powerful tool for reasoning about data. Attribute reduction is one of important topics in the research on the rough set theory. The classical rough set theory based on equivalence relation has made a great progress, while the equivalence relation is too harsh to meet and is extended to tolerance relation in real world. It is important to investigate rough computational...
The hybrid algorithm based on the chaos optimization algorithm and ant colony algorithm is proposed in this paper. It is an approach to solve the optimal operation issue of a reservoir. According to the randomness and ergodicity of chaos, by searching all the chaos variables and walking all the statuses, the hybrid algorithm can effectively increase the computing efficiency, is easy to improve the...
A feature fusion algorithm with application to facial expression recognition is presented. Firstly, the brows, eyes and mouth areas are segmented from the facial expression images, and are computed with Higher-order Local Auto-Correlation (HLAC) method, and the Weighted Principal Component Analysis (WPCA) is used to reduce dimensions secondly, in which the weights values are obtained according to...
