ORA-40271: no statistically significant features were found

Cause: Input data inadequate in volume and/or quality to derive statistically significant predictors for building a data mining model.

Action: Provide a well-prepared training data set.

ORA-40271: no statistically significant features were found 是Oracle统计机器学习(Statistical Learning or Scikit-Learn)的错误提示,用于指示模型无法从给定的数据中找到具有统计意义的特征。

官方解释

常见案例

一般处理方法及步骤

1.检查给定的数据集,以确保您有足够的有用特征来构建一个有效的模型;

2.如果现有特征不足,您可以添加新特征,但是应注意它们之间的相关性以避免出现ORA-40271;

3.如果现有的特征是有效的,但模型依旧无法从数据中提出有用信息,请尝试使用不同的模型,看是否能获得更好的结果。

4.如果模型还是没有显著特征,您可以尝试重新调整自己的参数,观察它们对结果的影响,以获得更好的预测结果。
