    "# 在测试数据集上比较不同的聚类算法\n",
    "\n",
    "这个例子展示了不同的聚类算法在数据集上的表现，这些数据集虽然有趣但仍然是2D的。除了最后一个数据集以外，每一个数据集的参数都经过调整为了产生更好的效果。一些算法对于参数值比其他算法更加敏感。\n",
    "\n",
    "最后一个数据集是一个\"null\"情况下的聚类：数据是同构的，没有良好的聚类。对于本例，null数据集使用与上面一行中的数据集相同的参数，这表示参数值和数据结构不匹配。\n",
    "\n",
    "这些例子虽然这些例子给出了一些关于算法的直觉，但这种直觉可能不适用于非常高维的数据。"
