I just read in the linked source Article (Brendan J. Frey; Delbert Dueck (2007). "Clustering by passing messages between data points"), that those equations are valid if the similarity function s is the negative square distance of two vectors. I went with the definition in the article and it ended up messing up my script. It is rather important to correct this. I am now only mentioning this for more experienced and confident wikipedions to take a look at.
Where it says, "... that is s(x_i, x_j) > s(x_i, x_k) iff x_j is more similar to x_i than x_k", it seems like the expression is literally saying that x_i is more similar to x_j than x_k. The expression doesn't match the English description of the expression's meaning. Is there a mistake here?Ecashin (talk)13:16, 25 September 2014 (UTC)[reply]
This article is clearly just a stub. Among other details, it needs to explain how one actually determines the clusters bases ona(i,k). Being an algorithm that doesn't require specifying the number of clusters, it's worth having a more thorough article about it. I assigned therefore an importance of Mid level.
Folks, I'm new here so pardon my ignorance. I had made a change to the Affinity Propagation page earlier and included a reference to a Ruby implementation of Affinity Propagation which I wrote.Melcous kindly explained to me the proper process specially to avoid conflict of interest. I'd like, therefore, to propose adding a reference to my Ruby implementation of the algorithm to the Software section. Something like:
* A [[Ruby (programming language)|Ruby]] implementation is available as the affinity_propagation gem.<ref>[https://github.com/sjaveed/affinity_propagation affinity_propagation gem]</ref>
While looking at the other Software listed on the page, too, I noticed that that reference to the Java Apro library is not a valid link any more and, to boot, is also not in the form of a reference. I'd like to propose we remove that from the Software section as well.
Not sure what the course of action is from here but please let me know!Thanks! --Sjaveed (talk)00:32, 15 November 2017 (UTC)[reply]
