Hi @fjiajin . ”Generalization hierarchy error“一般是因为定义的GH没有完全覆盖其中的部分取值(或者中间结果)。请检查下自己的GH:
- 不同节点是否有交集(不支持互相有交集的GH)
- 是否有特殊取值没覆盖,如*(缺失数据)
另外,请将Error message完整的贴出来,这样也方便我帮你诊断。

完全覆盖
的意思是。你定义的特定属性上的Generalization hierarchy,需要能够涵盖数据集中该属性所有取值。例如,【性别】需要包含男和女,如果少了女,而且如果数据集中女,就会报错。【学历】也是如此,如果有写学历没有被囊括进去,也会出错。

中间结果就是指gh中间的层次。GH就需要保证树形结构,其中平衡树效果会更好。把你的出错日志和gh发出来吧。不然实在没办法分析问题。
