SMOTE 节点

合成少数类过采样技术 (Synthetic Minority Over-sampling Technique, SMOTE) 节点提供了用于处理不平衡数据集的过采样算法。它提供了用于均衡数据的高级方法。SMOTE 过程节点使用 Python 进行实现并且需要 imbalanced-learn© Python 库。有关 imbalanced-learn 库的详细信息,请参阅 http://contrib.scikit-learn.org/imbalanced-learn/about.html1

节点选用板上的 Python 选项卡包含 SMOTE 节点和其他 Python 节点。
