Hudson commented on MAHOUT-294:
-------------------------------
Integrated in Mahout-Quality #155 (See
[http://hudson.zones.apache.org/hudson/job/Mahout-Quality/155/])
MAHOUT-294:
- modified most DisplayClustering subclasses to use the new sequential method
on drivers. (Not Dirichlet yet)
- using file system to transmit Clusters required a rework since they were not
serializing needed state
- refactored Canopy, Cluster, SoftCluster and MeanShiftCanopy significantly,
abstracting shared behavior to new AbstractCluster class.
- deleted ClusterBase after moving static method to AbstractCluster
- added ClusterObservations to replace KMeansInfo and FuzzyKMeansInfo
- changed all cluster identifier formatting to include type indication
- upshot of new clusters is improved posterior statistics for all with radius()
now returning stdDev(), a vector
- new radius() used in Display examples to show elliptical clusters
- adjusted unit tests and all pass
probably should have made a new JIRA for some of this

> * Move AbstractJob to common and convert all the Driver classes to extend
> that.
> One suggestion is:
> AlgorithmParams params = ParamsBuilder.build().withParam("-i",
> input).withParam("-o", output)....
> MyAlgorithmn.runJob(params) throws ParameterMissingException;
> * Give uniform command-line parameters for various algorithms.
> e.g Currently distance measure is -d, -dm, -m at different places in
> clustering
> * Add a temp directory as a parameter

> This issue will keep track of all discussion/patches related to the design
> and cleanup of Mahout API
