question: public static void writeCentroidsToFile ( Clusters clusters , FlagConfig flagConfig ) { VectorStoreRAM centroidsOutput = new VectorStoreRAM ( flagConfig ) ; for ( int i = 0 ; i < clusters . centroids . length ; ++ i ) { centroidsOutput . putVector ( Integer . toString ( i ) , clusters . centroids [ i ] ) ; } try { VectorStoreWriter . writeVectors ( "cluster_centroids.bin" , flagConfig , centroidsOutput ) ; } catch ( IOException e ) { e . printStackTrace ( ) ; } }
target:  Utility method that writes cluster centroids to a file called "cluster_centroids.bin".
