Java 可视化K-均值结果

我使用java中的java.ml库执行了K-means聚类。程序运行并向我返回一些结果。然而，我在可视化我的结果时遇到了困难，无论是图形化的还是其他的

下面是在我的数据集上运行10000次Kmeans（3个集群）的结果。 每行显示一个簇，单个向量包含在括号内，后跟向量标签。总共有20个向量。因此，每个向量有21个元素（20个元素包含每个向量的欧氏距离结果和1个标签）

---

有人能提出一种方法，以某种有意义的方式将这些结果形象化吗

在可视化高维数据时，我建议使用一种方法，将维数减少到2-3，并绘制它们。以下是两项建议：

• ，可以找到示例java实现
• ，您可以在Java中找到这些实现

---

当然还有其他方法来降低维度。尝试谷歌

降维

是否可以将任何一个集群中的数据项绘制为二维平面上的一个点？尝试使用ELKI（包括可视化）而不是java ml（多年来已经过时）。还要注意k-means不使用成对距离！
