Split and unfold¶
This processor splits the values of a column based on a separator and transforms them into several binary columns. Also called ‘dummification’.
For example, with the following dataset:
|1||login, product, buy|
|2||login, product, logout|
The unfolded column is deleted.
The limitations that apply to the “Unfold” processor also apply to the “Split and Unfold” processor.
