Outputs the Hadamard product (i.e., the element-wise product) of each input vector with a provided "weight" vector. In other words, it scales each column of the dataset by a scalar multiplier.
ft_elementwise_product(
x,
input_col = NULL,
output_col = NULL,
scaling_vec = NULL,
uid = random_string("elementwise_product_"),
...
)
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.
the vector to multiply with input vectors
A character string used to uniquely identify the feature transformer.
