A Gaussian kernel initialized with an appropriate sigma value.
Parameters
- inputs
- Type: SystemDouble
The data set.
Return Value
Type: GaussianA Gaussian kernel initialized with an appropriate sigma value.
Remarks
This method uses a simple heuristic to obtain appropriate values
for sigma in a radial basis function kernel. The heuristic is shown
by Caputo, Sim, Furesjo and Smola, "Appearance-based object
recognition using SVMs: which kernel should I use?", 2002.
