One Hot Encoder#
The One Hot Encoder takes a categorical feature column and produces an n-dimensional continuous representation where n is equal to the number of unique categories present in that column. A
0 in any location indicates that the category represented by that column is not present in the sample, whereas a
1 indicates that a category is present.
Data Type Compatibility: Categorical
This transformer does not have any parameters.
Return the categories computed during fitting indexed by feature column:
