我有一个由大约 10000 个样本组成的数据集，具有两个特征。我想使用 ELKI 来运行 LSDBC 算法并对我的数据集进行聚类。但是，我无法让 ELKI 工作。在运行 elki-0.7.0.jar 并将我想要的设置输入到 gui 之后，无论我选择什么设置，我都会在 gui 底部的控制台输入中收到一长串错误消息（我还没有能够输入我想要的所有设置）。这对我来说表明我缺少一些依赖项，错过了一些安装步骤，或者以某种方式没有正确使用该软件。

不幸的是，似乎没有很多关于 ELKI 的文档，但它也是我能够找到的 LSDBC 的唯一实现之一。我正在寻找的是逐步ELI5，在我的数据集（在WEKA创建的arff文件中）上安装和运行此算法并将结果输出为csv文件的说明；即一个输出文件，指示每个样本的聚类分配。我还希望能够对最佳 k 和 alpha 值执行网格搜索（即，针对 k 和 alpha 的多个值运行算法并保存每个结果；之后我将确定最佳值）。我正在使用 Mac OS X Yosemite。

我觉得这应该是一个相对简单的任务，但我一直没有取得任何进展。我已经复制了下面的错误流

The new ELKI 0.7.1 release

  • includes a README that tells you to use elki.bat or elki.sh to launch.
  • will display an easier to understand warning to tell you your classpath is incomplete.

Nevertheless, the audience of ELKI are developers that know how to read a stacktrace.

实际上有很多文档，在 JavaDoc 和 Wiki 中。

您的错误是非常基本的 Java 用法，与 ELKI 没有真正的关系。

从找不到的类名中可以看出（或谷歌）

gnu/trove/impl/hash/TObjectHash
java.lang.NoClassDefFoundError: gnu/trove/impl/hash/TObjectHash

您缺少GNU Trove Java 库（ELKI 的依赖项，但不是 ELKI 的一部分）。也许您没有下载完整的（单jar）版本，而只下载了最小的下载（假设您单独管理依赖项，或者已经拥有它们，例如通过使用流行的 Maven 工具）。
