"Association Rules Renaming results"
Hello.
I am working on association rules. I want rules about courses every semester. It works fine but the thing is that i want to rename the results.
For example "321-8354" corresponds to course "Networks", "321-8952" to "E-Management" etc...
Here is my code which does not work for "renaming" the results.

Use the Converters extension and conver them Assoc rules to an example set. Then use Replace (Dictionary) operator to mass convert your numbers.
Isn't this question similar to http://community.rapidminer.com/t5/RapidMiner-Studio-Forum/Rename-Premises-and-Conclusion-of-Association-Rules/m-p/38778 ?
You need to use Replace (Dictionary) if you want to rename them OR just have your data source convert them before you load it into RapidMiner.
