Subject [jira] [Updated] (SPARK-2429) Hierarchical Implementation of KMeans
Date Wed, 29 Oct 2014 13:16:33 GMT

     [ https://issues.apache.org/jira/browse/SPARK-2429?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Yu Ishikawa updated SPARK-2429:
-------------------------------
    Attachment: benchmark-result.2014-10-29.html

I added a new performance test results named `benchmark-result.2014-10-29.html`.  The main
change from the previous result is that I added the benchmark result about vector sparsity.
Please check it.

> Hierarchical clustering algorithms are widely used and would make a nice addition to
MLlib.  Clustering algorithms are useful for determining relationships between clusters as
well as offering faster assignment. Discussion on the dev list suggested the following possible
approaches:
> * Top down, recursive application of KMeans
> * Reuse DecisionTree implementation with different objective function
> * Hierarchical SVD
> It was also suggested that support for distance metrics other than Euclidean such as
negative dot or cosine are necessary.
