WebThe technique is to limit the one-hot encoding to 10 variable's most frequent labels. This means that we would make a binary variable only for each of the 10 most frequent tags, this is equivalent to grouping all other tags into a new category, which in this case will be eliminated. A) Yes, the 10 new dummy variables indicate whether one of the ... Web06. dec 2024. · OneHotEncoder from SciKit library only takes numerical categorical values, hence any value of string type should be label encoded before one hot encoded.
