Reads the XML parameters related to a generic algorithm stored in the ALGORITHM entity. An algorithm settings object captures the parameters associated with a particular algorithm. It allows a knowledgeable user to fine tune algorithm parameters. Generally, not all parameters must be specified, however, those specified are taken into account by the KDDML.
Implements kddml.Operators.AlgorithmResolverTask. |
|
Reads the data statistics related to the input discretization attribute. Data statistic can be used to provide additional information to preprocessing algorithm, such as the minimum and maximum value of the attribute.
Implements kddml.Operators.Preprocessing.NormalizationAlgorithms.NormalizationAlgorithmResolverTask. |
|
Normalizes the input value according to the normalization technique. Returns the normalized value.
Implements kddml.Operators.Preprocessing.NormalizationAlgorithms.NormalizationAlgorithmResolverTask. |
|
Returns a description of the actions performed by this preprocessing algorithm. This description will be reported in the history related to the preprocessing data source.
