我有一个数据集，包含大约10000个具有两个特征的样本。我想使用ELKI来运行LSDBC算法并对我的数据集进行聚类。但是，我还没能让ELKI工作。在运行elki-0.7.0.jar并将我想要的设置输入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获得大量错误消息（我还没有能够输入我想要的所有设置）。这对我来说表明我错过了一些依赖，错过了一些安装步骤，或者某种程度上没有正确使用该软件。
不幸的是，似乎没有关于ELKI的大量文档，但它也是我能够找到的LSDBC的唯一实现之一。我正在寻找的是一步一步，ELI5，在我的数据集（在WEKA创建的arff文件中）安装和运行该算法的指令，并将结果输出为csv文件;即一个输出文件，指示每个样本的簇分配。我还希望能够对最佳k和alpha值执行网格搜索（也就是说，运行几个k和alpha值的算法并保存每个结果;之后我将确定最佳值）。我使用的是Mac OS X Yosemite。
我觉得这应该是一项相对简单的任务，但我未能取得任何进展。我已经复制了我在下面的错误流

答案 0 :(得分：0)
实际上，JavaDoc和Wiki中有很多文档。
您的错误是非常基本的Java使用，与ELKI无关。
你可以告诉（或google）找不到类名
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（单jar）版本，而只下载了最小的下载（假设您单独管理依赖项，或者已经使用它们，例如使用流行的Maven工具）。 / p>
答案 1 :(得分：0)
新的ELKI 0.7.1版本
elki.bat或elki.sh启动。尽管如此，ELKI的观众是知道如何阅读堆栈跟踪的开发人员。
