"Using SOM clustering o/p to re-create original table with cluster-id column"

ruser

I have performed the SOM based Clustering using the following operators:
- DatabaseExampleSource
- SOMDimensionalityReduction
- ChangeAttributeRole

The i/p table format is here:
id attr1  attr2 ....... attr50
-------------------------------
0 val1  val2..................     
1 val3  val4..................
.........

I get the output like this:
id SOM_0
-----------
0    2
1    0
....

I would like to create a Table in the Database to include the cluster column with the original table. The new table should look like this:
id attr1  attr2 ....... attr50    SOM_0
------------------------------------------
0 val1  val2..................        2
1 val3  val4..................        0
.........

How do I achieve it using the Rapidminer operators?

Great! I found the answer myself :-)

I used the DatabaseExampleSetWriter to write the o/p of the SOM clustering into a new DB Table. Then, I can perform the Table 'join' operation to combine the original table with this new table. In the end, I have the desired result with the original table re-created with the Cluster-id column.

I like working with the Rapidminer.
