Neural Networks Methods of Extracting Rule from Database

Several methods of extracting rules from database using neural networks are surveyed in this paper:extracting rules based on BP network and BP algorithm using combining weight algorithm.Extracting fuzzy rules using fuzzy inferencing neural networks and CamDelta algorithm.Extracting fuzzy control rules from data based on the competitive neural networks and DCL algorithm.Discovering rules using the growing self-organizing map neural networks and hierarchical clustering algorithm.Extracting noncertainty rules using CFNet networks with certainty factor.Discovering rules numerical-linguictic data using fuzzy granular neural networks and heuristic learning algorithm.Finally,some confronting problems for extracting rules and ideas to solve are presented.And a rule extracting methods based on multiagent in distributed environment is contructed.6figs.,17refs.
