interface |
InPlaceInvertibleTransform
This interface behaves exactly as
InPlaceTransform specifies, with
the addition of an in-place "reverse" method that can be used to alter any
given transformed data point back into an approximation of the
original vector, without having to new vector object, but altering the one
given. |
Modifier and Type | Class and Description |
---|---|
class |
AutoDeskewTransform
This transform applies a shifted Box-Cox transform for several fixed values
of λ, and selects the one that provides the greatest reduction in the
skewness of the distribution.
|
class |
Imputer
Imputes missing values in a dataset by finding reasonable default values.
|
class |
InsertMissingValuesTransform
This transform mostly exists for testing code.
|
class |
LinearTransform
This class transforms all numerical values into a specified range by a linear
scaling of all the data point values.
|
class |
PNormNormalization
PNormNormalization transformation performs normalizations of a vector x by
one its p-norms where p is in (0, Infinity)
|
class |
StandardizeTransform
This transform performs standardization of the data, which makes each column
have a mean of zero and a variance of one.
|
class |
UnitVarianceTransform
Creates a transform to alter data points so that each attribute has a
standard deviation of 1, which means a variance of 1.
|
class |
WhitenedZCA
An extension of
WhitenedPCA , is the Whitened Zero Component Analysis. |
class |
ZeroMeanTransform
A transformation to shift all numeric variables so that their mean is zero
