what does "extractor_class " mean (FeatureExtraction operator)?

tsschmidt

The functionality of the FeatureExtraction operator is not enough for my needs. Mainly I miss a replace or a split method. May I could solve my problems with "extractor_class"? What does this mean?

It sounds like "write your own Java class", what would be not too bad.

Hi,

yes, the extractor class can be implemented by yourself. You simply have to implement the interface "FeatureExtractor", add the class to the RapidMiner / Java classpath during startup and specify the fully qualified class name for this parameter.

Cheers,
