The application of data processing based on variable precision rough set neural network in complex system

Data processing in the complex system generally the data is complicated and the data processing outcome is strictly. In order to deal with these problems researched the algorithm of variable precision rough set integrating neural network. It has powerful functions in data mining, data reducing and data classifying aspects. It is proofed by an example that this algorithm can process large and imprecise data in the complex system stably and rapidly and can mine the concealment knowledge in the large uncertainty data.
