It is presented in detail in the book Harmonic Analysis on Semigroups, by Berg, Christensen, and Ressel (1984), where the "squared distances" are called "negative definite kernels." This is also well known in the literature on kernel methods, e.g. Schoelkopf and Smola's Learning With Kernels (2001), where the negative of these squared distances appear under the name "conditionally positive definite kernels."AndrĂ© Martinshttp://www.blogger.com/profile/07656348479195514232noreply@blogger.comtag:blogger.com,1999:blog-6555947.post-45574949967457013312009-08-11T01:39:43.431-06:002009-08-11T01:39:43.431-06:00Just a little comment to say that I really like yo...Just a little comment to say that I really like your Blog!!
