Append (Robust)

Synopsis​

This operator works like the usual Append operator but it keeps all the nominal values even if they are not existing in all of the data sets but only in their meta data.

Description​

Just like the regular Append operator, this operator adds all the rows of all example sets into one merged set. However, this operator also keeps all nominal values in place even if they are not or no longer existing in all of the data sets. This can be useful to not break models in production since the meta data of the resulting data does not change in this case.

Input​

example set input​

These ports expects ExampleSets which all need to have the same attributes and value types and will be merged by appending all rows into one large set.

Output​

merged set​

The merged set of all input data sets where all meta data is still intact even if the values have no longer been a part of the input data sets.
