Herediscussed are the research background, architecture,implementation, development direction and hot issues of active networks.展开更多

Great mterest has been paid in data mining by researchers in different fields. In this paper,data mining techniques are introduced broadly including its definition,purpose,characteristic, principal processes and classifications. As an example,the studies on the mining association rules are illustrated. At last,some data mining prototypes are provided and several research trends on the data mining are discussed.展开更多
