MinMaxScaler()
Transform features by scaling each feature to a given range.
This estimator scales and translates each feature individually such that it is in the given range on the training set, e.g. between zero and one.
Methods
__repr__
__repr__()
Print the estimator's constructor with all non-default parameter values.
fit
fit(
X: typing.Union[bigframes.dataframe.DataFrame, bigframes.series.Series], y=None
) -> bigframes.ml.preprocessing.MinMaxScaler
Compute the minimum and maximum to be used for later scaling.
Parameters | |

Name | Description |
X |
bigframes.dataframe.DataFrame or bigframes.series.Series
The Dataframe or Series with training data. |
y |
default None
Ignored. |
Returns | |
---|---|
Type | Description |
MaxAbsScaler |
Fitted scaler. |
fit_transform
fit_transform(
X: typing.Union[bigframes.dataframe.DataFrame, bigframes.series.Series],
y: typing.Optional[
typing.Union[bigframes.dataframe.DataFrame, bigframes.series.Series]
