Andrew Musselman commented on MAHOUT-1539:
------------------------------------------
I'd say start with something commonly used, like vectors.
Please make a pull request as soon as you can so we can look at actual code
rather than just concepts, then develop from there.
> Implement affinity matrix computation in Mahout DSL
> ---------------------------------------------------
>
> Key: MAHOUT-1539
> URL: https://issues.apache.org/jira/browse/MAHOUT-1539
> Project: Mahout
> Issue Type: Improvement
> Components: Clustering
> Affects Versions: 0.9
> Reporter: Shannon Quinn
> Assignee: Shannon Quinn
> Labels: DSL, scala, spark
> Fix For: 0.10.1
>
> Attachments: ComputeAffinities.scala
>
>
> This has the same goal as MAHOUT-1506, but rather than code the pairwise
> computations in MapReduce, this will be done in the Mahout DSL.
> An orthogonal issue is the format of the raw input (vectors, text, images,
> SequenceFiles), and how the user specifies the distance equation and any
> associated parameters.
