Similarity example mismatch?[edit]

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)

What is meant is: "s(xi, xj) > s(xi, xk) iff the similarity between xi and xj is greater than that between xi than xk", but that seemed rather repetitive. Any suggestions on how to clarify this? QVVERTYVS (hm?) 18:30, 25 September 2014 (UTC)
I just updated the subscripts to match the definition, now that you've confirmed my reading of the text. Thanks! Ecashin (talk) 14:33, 26 September 2014 (UTC)

Quality and importance[edit]

This article is clearly just a stub. Among other details, it needs to explain how one actually determines the clusters bases on a(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.
