基于量化限制容差关系的数据填充算法研究
RESEARCH ON DATA FILLING ALGORITHM BASED ON QUANTITATIVE CONSTRAINED TOLERANCE RELATION
摘要
Abstract
Based on the analysis of the ROUSTIDA algorithm based on the tolerance relation and the VTRIDA algorithm based on the quantitative tolerance relation in the rough set model,a data filling method based on the integrated quantitative tolerance relation and the tolerance relation was proposed.VLTA (Valued and Limited Tolerance Algorithm) overcame the shortcomings of ROUSTIDA which could not fill the same attribute under the conflict of nondiscriminant object attribute value,and improved the quantization definition of VTRIDA to the unreasonable tolerance relation.Experiments showed that the VLTA algorithm had higher accuracy and more realistic results.关键词
