Apply Same Preprocessing to Learning and Validation Data

Created: 2010-05-19 10:36:57

This process demonstrates how to apply the same prepossessing work flow to learning data and test/validation data.

Due to overview reasons the preprocessing is hidden in a Preprocessing subprocess.

To perform the same preprocessing work flow on the learning and testing data, both are collected to a Collection of Data. Then the "Loop Collection" operator loops over each collection.

The actual preprocessing is done inside the "Loop Collection" operator. In the example only a "Rename" is done. Afterwards the Collections are split into the learning and testing data again.
