2 results about "Rough set" patented technology

In computer science, a rough set, first described by Polish computer scientist Zdzisław I. Pawlak, is a formal approximation of a crisp set (i.e., conventional set) in terms of a pair of sets which give the lower and the upper approximation of the original set. In the standard version of rough set theory (Pawlak 1991), the lower- and upper-approximation sets are crisp sets, but in other variations, the approximating sets may be fuzzy sets.

The invention discloses a data mining system. The data mining system comprises a data mining terminal which is used for mining data, meeting conditions preset by a user, in a network and is connected into the network through a bus. The data mining terminal further comprises a configuration module, a recognition module and a storage, the configuration module is used for configuring data mining conditions, a data structure and a data type, the recognition module is used for recognizing physical layers, link layers and application protocol layers of the network, and the storage is used for storing the configured data mining conditions and data obtained through mining according to the configured data structure and the data type. The data mining system has the advantages that data mining methods such as a statistic analysis method, a decision-making tree method, a rough set method, a fuzzy set method, a reasoning method based on models and a neural network method are used for analyzing, processing, reasoning and predicting the mass data in an information data set, and finally the optimal scheme is pushed automatically according to the conditions set by the user.
