A radial basis function (RBF) is a real-valued function $${\textstyle \varphi }$$ whose value depends only on the distance between the input and some fixed point, either the origin, so that $${\textstyle \varphi (\mathbf {x} )={\hat {\varphi }}(\left\ \mathbf {x} \right\ )}$$, or some other fixed point See more Radial basis functions are typically used to build up function approximations of the form where the approximating function $${\textstyle y(\mathbf {x} )}$$ is represented as a … See more The sum can also be interpreted as a rather simple single-layer type of artificial neural network called a radial basis function network, with the radial basis functions taking on the role of the activation functions of the network. It can be … See more • Matérn covariance function • Radial basis function interpolation • Kansa method See more Radial basis functions are used to approximate functions and so can be used to discretize and numerically solve Partial Differential Equations (PDEs). This was first done in 1990 by E. J. Kansa who developed the first RBF based numerical method. It is called the See more • Hardy, R.L. (1971).
