[jira] [Created] (MAHOUT-1659) Remove deprecated Lanczos solver
from spectral clustering in mr-legacy
Shannon Quinn created MAHOUT-1659:
-------------------------------------
Summary: Remove deprecated Lanczos solver from spectral clustering in mr-legacy
Key: MAHOUT-1659
URL: https://issues.apache.org/jira/browse/MAHOUT-1659
Project: Mahout
Issue Type: Task
Components: Clustering, mrlegacy
Affects Versions: 0.9
Reporter: Shannon Quinn
Assignee: Shannon Quinn
Priority: Minor
Fix For: 0.10.0
Spectral clustering still has the option of using either SSVD or the Lanczos solver for dimensionality reduction. Remove the latter entirely.

Are the slides from these talks going to be posted somewhere?

Different Topic: There's a talk this afternoon by Cloudera's Data Scientist
at MlConf NYC about Mahout's LanczosSolver, SSVD and MlLib SSVD.
See http://mlconf.com/mlconf-2015-nyc/
Here we r talking about purging Mahout's LanczosSolver for 2 years now.
Seems like the talk will be about the old MapReduce based SSVD and
LanczosSolver while we have
the new non-MR distributed SSVD stuff. I hope I am wrong here but will see.

Honestly not sure, as I haven't had a chance to play around with the
scala dsl much yet. Suneel suggested we save that for 0.10.1.

Shannon,
How difficult would it be to port spectral clustering to our scala alg and
math? We have ssvd there as well.
