Proposed merge with Similarity matrix[edit]

Same concept; a similarity matrix on a set of points/objects {} can be defined as for all i, j using a similarity measure (function) s. I.e. it's the Gram matrix of a similarity measure. QVVERTYVS (hm?) 10:54, 6 October 2013 (UTC)

As a practical point, if any merging is done, merge this article into similarity matrix and then rename if needed. Just for the purposes of the article history. Op47 (talk) 22:08, 23 January 2014 (UTC)
Done. QVVERTYVS (hm?) 21:32, 21 January 2016 (UTC)

is the given definition of s(xi,xk) correct? should it be exp(-||xi - xk||^2) instead? — Preceding unsigned comment added by (talk) 06:42, 19 March 2015 (UTC)
