public class WindowExamples2ModelingData
extends AbstractSeriesProcessing

This operator performs several transformations related to time series predictions based on a windowing approach. Those transformations could be performed with basic RapidMiner operators but lead to complex operator chains. Therefore, this operator can be used as a shortcut macro.

The basic idea is to apply this operator on a windowed data set like those create be the (Multivariate)Series2WindowExamples operators. Please note that only series data sets where the series was represented by the examples (rows) are supported by this operator due to the naming conventions of the resulting attributes.

This operator performs three basic tasks. First, it removed all attributes lying between the time point zero (attribute name ending "-0") and the time point before horizon values. Second, it transforms the corresponding time point zero of the specified label stem to the actual label. Last, it re-represents all values relative to the last known time value for each original dimension including the label value.

Method Detail

apply

public ExampleSet apply(ExampleSet exampleSet)
                 throws OperatorException

Description copied from class: AbstractExampleSetProcessing

Delegate for the apply method. In most cases, the returned example set will be the same as the example set or a modified clone.

Specified by:

apply in class AbstractExampleSetProcessing

Throws:

OperatorException

getParameterTypes

public java.util.List<ParameterType> getParameterTypes()

Description copied from class: Operator

Returns a list of ParameterTypes describing the parameters of this operator. The default implementation returns an empty list if no input objects can be retained and special parameters for those input objects which can be prevented from being consumed.

Specified by:

getParameterTypes in interface ParameterHandler

Overrides:

getParameterTypes in class Operator
