Hi All,
The svm formula, saying the simplest linear one: w*x+b=y.
Where w is the normal vectors of the hyper plane and can be calculated by
sum(alpha(i)*y(i)*x)
The values of ksvm of kernlab has alpha, coef, ymatrix, xmatrix and b. b is
sure the offset. How are the others related ? alpha = alpha, ymatrix= y, and
xmatrix = x? what is coef ?
Thanks a lot!
Regards,
Yan
