Subject [jira] [Commented] (FLINK-1707) Add an Affinity Propagation Library Method
Date Mon, 27 Jun 2016 15:13:52 GMT

    [ https://issues.apache.org/jira/browse/FLINK-1707?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15351211#comment-15351211

Josep Rubió commented on FLINK-1707:

Agree, I put this same statement in the design doc. But the paper does not explain that running
in parallel the calculations of E and I vertices of the binary model gives different intermediate
results as it has a different scheduling but I think it should give same clusters (but I'm
not an expert in bayesian networks). 

About the Capacitated Affinity Propagation, one of the advantages of the binary model is that
adding constraints to clusters means you just need different calculations for E and I messages.
In CAP case only the α(i,j) calculation is different so this means you just need to modify
the functions that updates E vertices.

By the way, I'm not sure I understand your answer. Do you mean we should work with the original
AP algorithm?

> This issue proposes adding the an implementation of the Affinity Propagation algorithm
as a Gelly library method and a corresponding example.
> The algorithm is described in paper [1] and a description of a vertex-centric implementation
can be found is [2].
