Abstract
The wavelet packet analysis was adopted in acquisition of fault diagnosis system´s characteristic parameter. The application of rough set theory in parameter´s attribute optimization was explored. The unnecessary attributes were eliminated with reduction algorithm. The inner redundancy of fault diagnosis system´s condition attributes is revealed. The complexity of neural network´s structure is also decreased. The result of attribute reduction is given finally.
