MaxAbsScaler()

Scale each feature by its maximum absolute value.

This estimator scales and translates each feature individually such that the maximal absolute value of each feature in the training set will be 1.0. It does not shift/center the data, and thus does not destroy any sparsity.

Methods

MaxAbsScaler

MaxAbsScaler()

Scale each feature by its maximum absolute value.

This estimator scales and translates each feature individually such that the maximal absolute value of each feature in the training set will be 1.0. It does not shift/center the data, and thus does not destroy any sparsity.

__init__

__init__()

API documentation for __init__ method.

fit

fit(X, y=None)

Compute the maximum absolute value to be used for later scaling.

Returns
Type	Description
MaxAbsScaler	Fitted scaler.

fit_transform

fit_transform(X, y=None)

Fit to data, then transform it.

Parameters
Name	Description
X	bigframes.dataframe.DataFrame or bigframes.series.Series Series or DataFrame of shape (n_samples, n_features). Input samples.
y	bigframes.dataframe.DataFrame or bigframes.series.Series Series or DataFrame of shape (n_samples,) or (n_samples, n_outputs). Default None. Target values (None for unsupervised transformations).

Returns
Type	Description
bigframes.dataframe.DataFrame	DataFrame of shape (n_samples, n_features_new). Transformed DataFrame.

get_params

get_params(deep=True)

Get parameters for this estimator.

Parameter
Name	Description
deep	bool, default True Default True. If True, will return the parameters for this estimator and contained subobjects that are estimators.

Returns
Type	Description
Dictionary	A dictionary of parameter names mapped to their values.

to_gbq

to_gbq(model_name, replace=False)

Save the transformer as a BigQuery model.

Parameters
Name	Description
model_name	str The name of the model.
replace	bool, default False Determine whether to replace if the model already exists. Default to False.

transform

transform(X)

Scale the data.

Returns
Type	Description
bigframes.dataframe.DataFrame	Transformed result.
