Counts the number of unique elements in each list/array of the input column.
The following example shows how the step can be used in a recipe.
Examples
This step has no configuration parameters, so it’s simply:
The following are the inputs expected by the step and the outputs it produces. These are generally
columns (ds.first_name
), datasets (ds
or ds[["first_name", "last_name"]]
) or models (referenced
by name e.g. "churn-clf"
).
Inputs
A column containing lists.
Outputs
The count of unique elements for each input list.
The following parameters can be used to configure the behaviour of the step by including them in
a json object as the last “input” to the step, i.e. step(..., {"param": "value", ...}) -> (output)
.
Parameters
This step doesn’t expect any configuration.
