On the other hand , adaptive method can save running time of iterations by increasing the sparsity of markov hyperlink matrix
另一方面， adaptive方法通过将马尔可夫超链接矩阵稀疏化以达到节省迭代时间的目的。
One is based on the discriminated matrics , the other is based on ga . we use many new ways to make the algorithms more effective , such as reducing dimension and sparsiting elements of the discriminated matrics , effectively selecting elements of the positive examples set and the counter examples set for the jointing - spreading matrics , using a new selecting operator , and so on
其次，实现了基于粗集理论的属性约简方法? ?基于可分辨矩阵的属性约简法和基于遗传算法的属性约简法，并通过降维、稀疏化、正例集和反例集的有效选取、新的选择算子等方法对原算法进行了改进。
