这可以通过使用le.inverse_transform()方法来实现。 总结:Label Encoding是一种简单的方法,用于将分类变量转换为机器学习模型可以理解的格式。它可以用于小规模数据集,但在处理大规模数据集时可能需要更复杂的标记方法。在使用Label Encoding时,应该注意将编码后的数据转换为数值型数据类型,并可能需要反向转换以获得原始类...

ENCODINGCurrently, there is a significant amount of public code in the IT communities, programming forums and code repositories. Many of these codes lack classification labels, or have imprecise labels, which causes inconvenience to code management and retrieval. Some classification methods have been ...

Force users to perform label encoding on their own. This will break existing code usingXGBClassifier. If the label is a cuDF series, convert it automatically into a NumPy array. This is inefficient (causing PCIe transfer) but does not break existing code. ...
