RapidMiner ETL - Transforming Attributes with Functions

In this video I show how to transform features in RapidMiner using operators such as log, sqrt, absolute value, and multiplying columns.


  1. Hi all,

    The transform functions identified in the default transform group named DB2_FUNCTION are used whenever a user-defined function or method not written in SQL is invoked using the data type type-name as a parameter or returns type. This applies when the function or method does not specify the transform group clause. Thanks a lot......

  2. Thank you, all ETL are great!!!

    Now I have a better idea for working.

    Do you have any videos on series?
