Conditionally positive definite function
WebBesides Guassians, there are several other well known of positive definite functions, and also another class called conditionally positive definite functions which allow for polynomial reproduction. Such an example is the thin plate spline, which is a radial function defined from the univariate function $\phi(r) = r^2 \log(r)$. WebExperimentalists frequently gather spectral data when the observed data is limited, e.g., by the precision of instruments; or by other limiting external factors. Here the limited information is a restriction, and the extensions take the form of full positive definite function on some prescribed group. It is therefore both an art and a science ...
