当前正在从事教育数据挖掘项目。我的某些数据集遇到一个非常常见的问题，无法在任何地方搜索此问题。每当我运行流程时，状态始终会显示
“仅一个标签”，学习方案Logistic回归不足以处理仅带有一个标签的示例集。如果仅知道一个类的示例，则存在现有的特殊建模运算符。它们支持“一类标签”功能。
我得到了一些带有一个标签的数据集，并且效果很好。我还尝试编辑标签，因为我使用了多重标签。我不明白这个问题。请帮助大家！下面是我的XML。

答案 0 :(得分：0)
）（无法访问数据），我想问题是您尝试训练逻辑回归的数据集只有一个标签类（例如，只有TRUE，没有FALSE）。如果您的示例集包含很少的示例，并且偶然地只有一个班级参加了培训，那么这也可能发生。
关于显示的过程，我也想知道，当您只有一个标签列名为“ overall-remarks”时，为什么要使用 Multi Label Modeling 。在这种情况下，正常的分类策略应该可以正常工作。
有关流程设计的更多信息和详细讨论以及有关RapidMiner的一般问题，我还建议您在RapidMiner社区中重新发布您的问题：https://community.rapidminer.com
