Abstract :
The mass dataset based on static reduct concludes large instability. A new thought is provided by dynamic reduct. The thought of dynamic reduct is described, its subtable extracting problem is analyzed in detail, and the shortage is pointed out. A new algorithm is given to calculate the size of the dynamic reduct subtable family, and some parameters are also presented to evaluate the dynamic reduct sampling family.
