-----------------------------------
Summary: Nearest neighbor searchers sometimes fail to remove points
Key: MAHOUT-1217
URL: https://issues.apache.org/jira/browse/MAHOUT-1217
Project: Mahout
Issue Type: Bug
Components: Math
Affects Versions: 0.8
Reporter: Dan Filimon
When updating a Centroid in StreamingKMeans, the Centroid needs to be removed
and its updated version added.
When removing points in a searcher that are already there, sometimes the
searcher fails to return the closest point (the one being searched for) causing
a RuntimeException.
This has been observed for TF-IDF vectors with SquaredEuclideanDistance and
CosineDistance and FastProjectionSearch.
