RBFPREIMG3 |
RBF pre-image problem by Kwok-Tsang's algorithm.
Synopsis:
x = rbfpreimg3(model)
x = rbfpreimg3(model,nn)
Description:
x = rbfpreimg3(model) is an implementation of the algorithm
by [Kwok03] to solve the pre-image problem for kernel expansion
with RBF kernel. The kernel expansion is given in the input
structure model.
x = rbfpreimg3(model,nn) use to set number of nearest
neighbours (default 10).
Input:
model [struct] RBF kernel expansion:
.Alpha [nsv x 1] Weights.
.sv.X [dim x nsv] Vectors.
.options.arg [1x1] RBF kernel width.
nn [1x1] Number of nearest neighbours.
Output:
x [dim x 1] Pre-image of the RBF kernel expansion.
