----------------------------------------
Paritosh,
I'm running into a strange issue, I've refactored the FuzzyKMeansDriver similar
to KMeansDriver and to use the FuzzyKMeansClusteringPolicy with the other logic
being pretty much the same. The unit test for FuzzyKMeansDriver when run
individually passes, however the unit test fails when I go to run all the unit
tests together. I am attaching the clusterData function here, any ideas on
this?
Regards
public static void clusterData(Path input,
Path clustersIn,
Path output,
DistanceMeasure measure,
double convergenceDelta,
float m,
boolean emitMostLikely,
double threshold,
boolean runSequential)
throws IOException, ClassNotFoundException, InterruptedException {
if (log.isInfoEnabled()) {
log.info("Running Clustering");
log.info("Input: {} Clusters In: {} Out: {} Distance: {}", new Object[]
{input, clustersIn, output, measure});
}
ClusterClassifier.writePolicy(new
FuzzyKMeansClusteringPolicy((double)m,convergenceDelta), clustersIn);
ClusterClassificationDriver.run(input, output, new Path(output,
CLUSTERED_POINTS_DIRECTORY),
threshold, true, runSequential);
}
