---------------------------------------
Summary: CLONE - Additional computation methods for k-NN
Key: MADLIB-1129
URL: https://issues.apache.org/jira/browse/MADLIB-1129
Project: Apache MADlib
Issue Type: Improvement
Components: k-NN
Reporter: Frank McQuillan
Fix For: v2.0
Follow on to
https://issues.apache.org/jira/browse/MADLIB-927
which uses brute force.
Determine other k-NN algos to implement. From
http://scikit-learn.org/stable/modules/neighbors.html
candidates are:
* K-D Tree
* Ball Tree
* Other?
Look at how to implement in a distributed way. Also may want to revisit
current brute force approach to see if there are improvements to make on
parallelism - testing is in serial currently.
