Aiming at the problem of attribute reduction in rough set theory, the polarization matrix and relative degree are defined, and then, an approach to minimum attribute reduction is presented. The typical example of decision table shows that it is feasible and effective. In the oil-gas reservoir test, the approach to minimum attribute reduction is applied to optimize the seismic attributes with the notable...
In order to overcome the disadvantages that the traditional k-nearest neighbor classification technique makes inadquate use of distribution characteristics of homegeneous data, and that it is of slow speed and low efficiency, an effective data classification algorithm based on the decision table grid is presented. The main process is to construct the corresponding decision table after discretizing...
