Kernel functions can capture complex and nonlinear patterns in the data, such as curves, circles, and spirals. Some common kernel functions are linear, polynomial, radial basis function (RBF), and ...

Abstract: Two forms of a sampling theorem for concentric circles are established for a bandlimited two-dimensional (2-D) function. The location of the samples is prescribed either on equidistant ...
