Label Encoding: Naming the Unnamed Categories – Let’s Data Science
Label Encoding is an essential step in this learning process. By converting categories into numbers, Label Encoding helps the model understand the data better. This results in a model that can learn more accurately from the data and make better predictions. Comparison with numerical data processing.

Encoders — How To Write Them, How To Use Them
In order to have both the Label Encoder and the Ordinal Encoder work very effectively at their tasks, they needed to be separate. The big difference between these two is that the Label Encoder is typically used for targets, whereas the Ordinal Encoder is typically used to encode features — that’s it! So if you’re wondering what the code …
