Normalizes a numerical column by subtracting the mean and dividing by its standard deviation.
The resulting column’s values will have a mean of 0.0 and a standard deviation of 1.0.
Both types of scaling can be toggled separately via the with_mean
and with_std
parameters.
The following examples show how the step can be used in a recipe.
Examples
To normalize using both mean and standard deviation:
To normalize using both mean and standard deviation:
Using a custom configuration to only subtract the mean:
General syntax for using the step in a recipe. Shows the inputs and outputs the step is expected to receive and will produce respectively. For futher details see sections below.
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 numeric column to normalize.
Outputs
A numeric column containing the normalized value.
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)
.
