Normalize a vector to have unit norm using the given p-norm.
ft_normalizer(
x,
input_col = NULL,
output_col = NULL,
p = 2,
uid = random_string("normalizer_"),
...
)The object returned depends on the class of x. If it is a
spark_connection, the function returns a ml_estimator or a
ml_estimator object. If it is a ml_pipeline, it will return
a pipeline with the transformer or estimator appended to it. If a
tbl_spark, it will return a tbl_spark with the transformation
applied to it.
A spark_connection, ml_pipeline, or a tbl_spark.
The name of the input column.
The name of the output column.
Normalization in L^p space. Must be >= 1. Defaults to 2.
A character string used to uniquely identify the feature transformer.
Optional arguments; currently unused.
