Dynamic multi-stage discrete method of continuous attributes based on absolute degree of grey incidence and balance degree of grey entropy

Based on the optimality principle, the article makes grading dynamic optimization discretization about the problem that amount of calculation of small samples discretization and overall dynamic discretization samples are large in the process of mold material attributes discretization, and makes research and discussion on absolute degree of grey incidence; measures data degree of discrete interval based on a balance degree in grey entropy theory in the process of data discretization. On this basis, dynamic discrete method of mold material attributes based on Absolute degree of grey incidence and Balance Degree of Grey Entropy is mentioned.
