In recent years, time series data mining has already been an important branch of data mining. In this paper, an improved sequential pattern mining algorithm PBGC ( sequential pattern mining algorithm based on general constraint) is presented, in which seismic knowledge is used as general constraint to restrict the sequential patterns, and eventually(More)
In this paper, after discussing classical rough set theory based on indiscemibility relation and the problem of its reduction algorithms on Seismology Data, we arrived at a new definition of dominance distinguishing matrix by taking advantage of the unique characteristic of the extended model. Then the corresponding reduction and rule extracting algorithms(More)
