Hi All,

I'm developing a ksvm application. I need to use the results obtained from ksvm in R to construct or restore the ksvm formula and further use this formula to predict new data.

The ksvm class contains xmatrix, ymatrix, coefficients, alpha, b and fitted value. Taking linear svm as an example ( vanilladot), the formula is like :

     F(x) = sign(sum(w*x*y*z)+b)

Where, x =  xmatrix, y = ymatrix, b is intercept and z is the input matrix? The w is alpha or coefficient from ksvm class? I did some calculation but the result is not the same as the fitted value.

Can you give me some idea on the prediction of ksvm by the formula?

Thanks a lot!!!

Regards,
Yan
