Changeset 10676 for branches/DataPreprocessing/HeuristicLab.DataPreprocessing

Timestamp:

03/27/14 12:49:33 (10 years ago)

Author:

Message:

• Data preprocessor now works with all types of data analysis problems. Only in case of a symbolic data analysis problem the inverse transformation information is added.

Location:

branches/DataPreprocessing/HeuristicLab.DataPreprocessing/3.3

Files:

• Implementations/PreprocessingContext.cs (modified) (5 diffs)
• Interfaces/IPreprocessingContext.cs (modified) (2 diffs)
