英文摘要：

Aiming at the polybasic and heterogeneous characteristics of uncertainty industrial data,a rough set attribute reduction algorithm was proposed.The attribute kernel parameter of rough set was taken as immune bacterins to encode the antibody.A niche immune memory was introduced in clonal selection process to optimize with sharing mechanism coordinately,which could overcome the blindness of crossover and mutation operators,improve the diversity and stability of antibody distribution and promote the preservation of excellent individual in original antibody group and memory base.By optimizing the approximate standard of attribute classification,the ability of excellent individual to get clone expansion was improved and the opportunity of affinity maturation was realized.Simulation experimental result illustrated that the approach was an effective and quick way in solving industry data attribute reduction.
