与partitional相关的网络例句 [注：此内容来源于网络，仅供参考]

The best theoretical solution to a partitional clustering problem is to find all possible partitions and choose the partition that minimizes the objective function. However, the enumeration of all possible partitions is impractical even for data sets of moderate size. Therefore, as an alternative, most partitional approaches use an iterative optimization technique. And this could be cause local minimum.

本文在分析了目前聚类的基本方法的基础上，指出以K平均法等为代表的分割聚类虽然理论上找到类的所有划分并使得目标函数最小就可以获得最优解，但由于对于相当尺度的数据集列举所有可能的划分并不现实，因而多数分割方法采用迭代优化技术作为变通。

The 2D images were obtained by the partitional microphotography on each brain section.

采用分区显微摄影法，获取每张脑组织切片的二维图像。

Finally, the problems existing in these algorithms and the prospects of the fuzzy partitional algorithms are discussed.

最后总结了基于划分的模糊聚类算法普遍存在的问题及其发展前景。

partitional clustering：分割式分群法

在使用分割式分群法(partitional clustering)时,我们必须先指定群聚的数目,然后藉著反覆叠代运算,逐次降低一个误差目标函数的值,直到目标函数不再变化,就达到分群的最后结果.
