你好,可以用weka的PCA,对降维的结果进行处理的方法可以参考这两篇论文
Maria C. Uyarra, Isabelle M. C & Ocirc. Island-specific preferences of tourists for environmental features: implications of climate change for tourism-dependent states. Environmental Conservation, Volume 32, Issue 01, March 2005, pp 11 – 19.
William R. Dillon, Narendra Mulani, Donald G. Frederick. On the use of component scores in the presence of group structure. Journal of Consumer Research, Vol. 16, No. 1 (Jun., 1989), pp. 106-112.
不过处理的过程不侧重属性的排名而是对特征意义的归类和分析,比较适用于维数较少的数据。希望对你有帮助:) |
