In order to study wind power medium-term forecast method, a combined forecasting method is proposed in this paper, taking gray theory and neural network to combine to forecast wind power of wind farm. Through establishing metabolism gray forecast model, using the linear weighted method to take gray information metabolism model and chaotic neural network model for portfolio optimization, and simulated...
As the most popular information publishing platform, the Web contains a lot of valued information of interests to users or applications. Although a lot of data extraction techniques have been studied in the last decade, it is still far away from meeting the need of real data extraction. On the one hand, most of them cannot support the whole web information extraction process involving three stages:...
The Web is the largest data source that contains a lot of valuable information of interests to users or applications. However, how to automatically navigate and extract useful data from web pages is an important issue to study. There have been a number of existing studies on this area. However, most of them do not take enough consideration on complete process of web information extraction and lack...
Emergent computation is a relatively new approach for understanding the behaviors of complex systems. Central to this approach is the idea that system-level behavior emerges from interaction among individual elements. This paper proposes a network emergent computation model based on cellular automaton, which introduces network operating mechanism, such as store-and-forward, adjacency interaction,...
