Modifier and Type	Method and Description
void	fit(double[] input) The function only fits a single instance of the dataset
void	fit(double[][] input)
void	fit(TimeSeriesDataset input) the function computes the needed information for the transform function.
double[]	fitTransform(double[] input) the function fit and transforms a single instance
double[][]	fitTransform(double[][] input)
TimeSeriesDataset	fitTransform(TimeSeriesDataset input) a utility function to avoid the added effort of calling the fit and transform function separate
int	getDefaultWindowSize()
void	setDefaultWindowSize(int defaultWindowSize)
TimeSeriesDataset	specialFitTransform(double[] instance) This is an extra fit method because it does not return a double[] array even though it gets a double [] as input as it would be defined in the .
double[]	transform(double[] input) This function transforms only a single instance.
double[][]	transform(double[][] input)
TimeSeriesDataset	transform(TimeSeriesDataset input) represents a function working on a dataset by transforming the dataset itself.

transform

public TimeSeriesDataset transform(TimeSeriesDataset input)

Description copied from interface: IFilter

represents a function working on a dataset by transforming the dataset itself.

Specified by:

transform in interface IFilter

Parameters:

input - the data set that is to transform

Returns:

the transformt dataset

fit

public void fit(TimeSeriesDataset input)

Description copied from interface: IFilter

the function computes the needed information for the transform function.

Specified by:

fit in interface IFilter

Parameters:

input - the dataset that is to transform

specialFitTransform

public TimeSeriesDataset specialFitTransform(double[] instance)

This is an extra fit method because it does not return a double[] array even though it gets a double [] as input as it would be defined in the .

Parameters:

instance - that has to be transformed

Returns:

the tsdataset that results from one instance which consists of one matrix with each row represents one part of the instance from i to i+ window length for i < n- window length

fitTransform

public TimeSeriesDataset fitTransform(TimeSeriesDataset input)

Description copied from interface: IFilter

a utility function to avoid the added effort of calling the fit and transform function separate

Specified by:

fitTransform in interface IFilter

Parameters:

input - the dataset that is to be transfromed

Returns:

the transformed dataset

transform

public double[] transform(double[] input)

Description copied from interface: IFilter
