如何将“自动模型”从快速矿工保存到本地磁盘

Question

我已经使用 Rapid Miner 建立了一个回归模型。微调模型后精度很好。现在我想使用相同的模型文件来运行下一组数据。有没有办法将 RapidMiner 分类器模型导出到本地磁盘并预测新数据。

Answer 1

要访问 AutoModel 结果，请单击结果视图中的“打开流程”。然后您可以右键单击第三个输出端口（用于模型）或重新运行该过程，然后通过右键单击模型选项卡标题来存储模型。

通常，您可以将任何模型存储在 RapidMiner 存储库中。通过右键单击结果视图中的选项卡标题，或在模型输出端口后使用 "Store" 运算符。

如果您想在新数据上运行模型，请使用 "Apply Model" 运算符，以及存储的模型和新数据集。

请参阅教程流程以获取示例（只需将 XML 复制并粘贴到您的流程窗口中）。 您还可以查看 RapidMiner 社区以获取更多培训材料：
