Abstract: Dynamic updating the upper and lower approximations in multi-granulation rough sets based on column matrix mainly use the relative correct classification rate to consider the varying attribute values and varying universe simultaneously. First, we discuss some properties of upper and lower approximation operators of multi-granulation rough sets while the universe decreasing and adding attributes, and give an updating method for approximations based on column matrix. Second, we discuss some properties of approximation operators while the universe decreasing and adding attributes, and give an updating method based on column matrix. The methods we proposed effectively shrink the searching region when updating the approximations of the multi-granulation rough sets.

Key words: incremental computing, updating approximation, multi-granulation rough set, column matrix
