Label Encoding, which consists of substituting a class with a fairly random integer, must be prevented in any respect prices when coping with non-ordinal classes due to the potential for the confusion it may trigger. One-Sizzling-Encoding and Goal Encoding are far superior alternate options to think about using as a substitute. One-Sizzling Encoding is probably probably the most extensively used method as a result of it capabilities admirably in real-world conditions (Zuccarelli, 2022). Goal Encoding is a much less well-known however doubtlessly fruitful method that not solely maintains the dimensionality of the dataset in a constant method but additionally improves efficiency.
