Rough set is a good tool for the math problem. The advantage of Rough set is the ability to acquire the knowledge. Today artificial neural network develops very fast. It has a lot of advantages, such as self-learning and self-organization. But it also has a problem. It is difficult to make a decision from it.
Rough set theory can make some improvements. Based on the theory of rough set, this dissertation studies rough set-artificial neural network. A newly reduced algorithm based on rough set the...
