Jeff Eastman commented on MAHOUT-931:
-------------------------------------
1. I don't see a reason to introduce ClusterConfigs yet. I believe the various
CLI arguments can be carried in the appropriate ClusteringPolicy
implementations.
2. Other than augmenting what exist already with some more CLI arguments, I
think this is done
3. Outlier removal is not a part of the buildClusters step, rather the
clusterPoints step. I thought you were going to work on those stories while I
finish up the mapreduce implementation of buildClusters using
ClusterIterator/Classifier/Policies (MAHOUT-933)? This story (MAHOUT-931)
should follow after -929 & -930, IMHO, for example:
- 929 implement a new post processor that does only classification as required
by the various clusterPoints steps.
- 930 modify the existing drivers to use this post processor rather than their
current, custom implementations.
- 931 modify the post processor to support pluggable outlier removal.
4. This can be done once -933 is complete.
In any case, this is all post-0.6 stuff. Let's leave trunk where it is with the
renaming for now.
