我正在完成我们研究中一种新的数据挖掘技术的实施。
我想从 rapidminer 中包含的定义的度量和性能运算符中获利，所以我需要向性能运算符提供一个标记的数据集。
谁能帮我找到如何创建标记数据集？（我有标签和预测，我的问题是如何以标签集的形式创建输出数据表）。

RapidMiner distinguishes between regular and special attributes. If you already have an example set with prediction and label attribute you have to change the role of these. But typically this roles are set when you import your data and the learning of the model.
You have to do this, because the performance operators expects two special attributes with the role 'label' and 'prediction'. Therefore, insert the "Set Role" operator before the performance operator and select the attribute name (use 'set additional roles' for more than one attribute) and the target role accordingly.
