Snippet Name: CLUSTER_ID
Description: CLUSTER_ID returns the cluster identifier of the predicted cluster with the highest probability for the set of predictors specified in the mining_attribute_clause. The value returned is an Oracle NUMBER.
The mining_attribute_clause behaves as described for the PREDICTION function.
This function is for use with clustering models that have been created using the DBMS_DATA_MINING package or with the Oracle Data Mining Java API.
This example, and the prerequisite data mining operations, including the creation of the dm_sh_clus_sample model and the dm_sh_sample_apply_prepared view, can be found in the demo file $ORACLE_HOME/rdbms/demo/dmkmdemo.sql.
