-----------------------------------------

Hi Ted,

Either one can use the Mahout-228 patch or just the lucene text vectorization 
already in there.  After that it looks more likley to run K-means.

> Implement the Clustering algorithm described in "A Framework for Clustering 
> Massive-Domain Data Streams" by Chary C. Aggarwal.
> Steps: 
> 1. Implement baseline solution to compare solutions.
> 2. Figure out how to implement the loading of clustering by looking at the 
> k-means implementation.
> 3. Implement Count-Min sketch algorithm for each cluster.
> 4. Find out how to give the user the power to choose the distance function 
> for the input data ( Maybe already possible? )
