Hudson commented on MAHOUT-1202:
--------------------------------
Integrated in Mahout-Quality #1983 (See
[https://builds.apache.org/job/Mahout-Quality/1983/])
Fixes MAHOUT-1202.
https://issues.apache.org/jira/browse/MAHOUT-1202
This issue relates to the design document at
https://docs.google.com/document/d/1g1PjUuvjyh2LBdq2_rKLIcUiDbeOORA1sCJiSsz-JVU/edit#heading=h.koi571fvwha3jj
(Revision 1478958)
Part of MAHOUT-1202.
Extended OrderedIntDoubleMapping to support merging and zero values.
This is required for faster SequentialAccessSparseVector updates. (Revision
1478865)
Part of MAHOUT-1202.
Makes DoubleFunction and DoubleDoubleFunction abstract
classes and adds method for a function class that can speedup vector operations
that check if a function has certain properties (is associative/commutative
etc.) (Revision 1478853)
Fixes part of MAHOUT-1155.
https://issues.apache.org/jira/browse/MAHOUT-1155
Doesn't update Centroid because that is now part of the larger Vector changes
in https://issues.apache.org/jira/browse/MAHOUT-1202. (Revision 1478836)
Result = SUCCESS

> Speed up Vector operations
> --------------------------
>
> Key: MAHOUT-1202
> URL: https://issues.apache.org/jira/browse/MAHOUT-1202
> Project: Mahout
> Issue Type: Improvement
> Components: Math
> Affects Versions: 0.8
> Reporter: Dan Filimon
>
> Vector assign() and aggregate() can be significantly improved in some
> conditions taking into account the different properties of the vectors we're
> working with.
> This issue relates to the design document at
> https://docs.google.com/document/d/1g1PjUuvjyh2LBdq2_rKLIcUiDbeOORA1sCJiSsz-JVU/edit#heading=h.koi571fvwha3jj
> and the patch at
> https://reviews.apache.org/r/10669
> The benchmarks are at
> https://docs.google.com/spreadsheet/ccc?key=0AochdzPoBmWodG9RTms1UG40YlNQd3ByUFpQY0FLWmc&pli=1#gid=10
> and while there are a few regressions (which will be fixed later regarding
> RandomAccessSparseVectors), it improves a lot of benchmarks as well as cleans
> up the code significantly.
> Part 1, the new function interfaces is merged. [Committed revision 1478853.]
