变精度粗糙集模型在空袭兵器类型识别中的应用

摘要

针对经典粗糙集模型解决空袭兵器类型识别问题时的不足，文章提出了一种改进的相似度，建立了基于改进相似度的变精度粗糙集模型并提出了基于重要度的属性约简算法。最后利用一组测试样本对模型进行了检验，结果表明模型准确、可靠。%When classical rough set theory is used to deal with the problem of type identification of airattack weapon there is some in sufficient. An improved similarity has been put forward, and then, variable precision rough set model has been established and a reduction al gorithm based on the significant degree is proposed. The model is validated by a set of test samples and the result shows that the model is ac curate and reliable.
