+这个例子演示了如何使用谱协聚类算法生成数据集并对其进行双聚类处理。
+
+数据集是使用 `make_biclusters` 函数生成的，该函数创建一个小值矩阵，并将大值植入双聚类。然后将行和列打乱并传递给光谱协聚算法。通过重新排列变换后的矩阵可以使双聚类连续，这展示出该算法找到双聚类的准确性。

+这个例子演示了20个新闻组数据集上的光谱协聚类算法。‘comp.os.ms-windows.misc’ 类别被排除在外，因为它包含许多只包含数据的帖子。
+
+TF-IDF 矢量帖构成一个词频矩阵，然后使用 Dhillon 光谱协聚算法对其进行重组。由此产生的文档词双聚类表明在这些子集文档中被使用频率更高的子集词。
+
+对于一些最好的双聚类来说，它最常见的文档类别和十个最重要的单词会被打印出来。最佳双类别由其归一化的切割决定。最好的单词是通过比较它们在两区内和两区外的总和来确定的。
+
+为了进行比较，我们还使用 MiniBatchKMeans 对文档进行集群。从双聚类衍生出的文档聚类比使用 MiniBatchKMeans 得到的聚类具有更好的 V-measure。
