Hi,
My goal is to transform the vectors created by lucene.vector (thanks to kmeans
clustering) to a human readable format. For that I am using ClusterDumper
function on eclipse. But that code does not generate none files. What am I
missing? What is the best approach to transform output of kmeans to a human
readable (no unix command please I am on windows using eclipse and cygwin).
This is the code:
Code :
Map<Integer, List<WeightedVectorWritable>> result =
ClusterDumper.readPoints(new Path("output/kmeans/clusters-0"), 2, conf);
System.out.println(result.get(0).toString());
for(int j = 0; j < result.size(); j++){
List<WeightedVectorWritable> list = result.get(j);
for(WeightedVectorWritable vector : list){
System.out.println(vector.getVector().asFormatString());
}
}
Error :
Exception in thread "main" java.lang.ClassCastException:
org.apache.mahout.clustering.iterator.ClusterWritable cannot be cast to
org.apache.mahout.clustering.classify.WeightedVectorWritable
at main.LuceneDemo.main(LuceneDemo.java:260)
Thank you
