Meethu Mathew commented on SPARK-4156:
--------------------------------------

We had run the GMM code on two public datasets :
 http://cs.joensuu.fi/sipu/datasets/s1.txt 
 http://cs.joensuu.fi/sipu/datasets/birch2.txt 

It was observed in both the cases that the execution converged at the 3rd 
iteration and the w , mu and sigma were identical for all the components.The 
code was run using the following commands:
./bin/run-example org.apache.spark.examples.mllib.DenseGmmEM s1.csv 15 .0001
./bin/run-example org.apache.spark.examples.mllib.DenseGmmEM birch2.csv 100 
.0001

Are we missing something here?
