KPCAREC

Reconstructs image after kernel PCA.


 
 Synopsis:
  Y = kpcarec(X,model)

 Description:
  Input data X are projected using kernel projection trained
  the by Kernel PCA [Mika99b]. The RBF kernel is assumed. This 
  function computes the preimages Y from the input space 
  corresponding to the projected data are.

   X -> projection to -> preimage -> Y
        kernel space     problem
        by Kernel PCA

 Input:
  X [dim x num_data] Input vectors.
  model [struct] Kernel projection with RBF kernel;
   see 'help kernelproj'. 

 Output:
  Y [dim x num_data] Output data.
