Greg Hogan commented on FLINK-1707:
-----------------------------------
>From the "A Binary Variable Model for Affinity Propagation" paper: "The α(i,j)
>messages are identical to the AP availability messages a(i,j), and the ρ(i,j)
>messages are identical to the AP responsibility messages r(i,j). Thus, we have
>recovered the original affinity propagation updates."
I'm rather uncertain what we are working towards here. This paper provides a
nice derivation of Affinity Propagation but the algorithm is unchanged which
should yield the same Flink implementation. The paper discusses "Capacitated
Affinity Propagation" which would be a separate algorithm and implementation.
> Add an Affinity Propagation Library Method

> 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].
