Reads the XML attributes related to a generic preprocessing operator. An operator settings object captures the attributes associated with a particular operator. It allows a knowledgeable user to fine tune operator parameters. Generally, not all parameters must be specified, however, those specified are taken into account by the KDDML.
Implements kddml.Operators.Preprocessing.PreprocessingResolver. |
|
Reads other arguments from the input vector, i.e. arguments whose position is different from the first. By default, this method do nothing. It must be overried if and only if the preprocessing operator accepts other arguments in addiction to the preprocessing table. In this case, also the method getArgumentType(int i) must be overried.
Reimplemented from kddml.Operators.Preprocessing.PreprocessingResolver. |
|
Reads data statistics related to input preprocessing table. Data statistic can be used to provide additional information to preprocessing operator, such as the number of total instances or attributes belonging to the data source. By default, this method do nothing. It can be overried inside operator implementation if necessary.
Reimplemented from kddml.Operators.Preprocessing.PreprocessingResolver. |
|
Returns a description of the actions performed by this preprocessing operator. This description will be reported in the history related to the preprocessing data source.
Implements kddml.Operators.Preprocessing.PreprocessingResolver. |
|
Core operator method. Given a physical instance and the related preprocessing tuple as weka.core.Instance, the operator returns the modified instances as two-dimensional array.
Implements kddml.Operators.Preprocessing.InstanceLevelIndependentTransformation. |
|
Returns the expected type of the i-th argument of the operator. Returns null if the operator do not admit argument as i-th child.

The estimated RAM usage for the operator. Must be a value between 0 and 1024 MB.
