how does class weights Parameter in LibSVM work?
how do the parameter setting for class weights in LibSVM work? e.g. if I have a class that is 2x less or 3xless than my main class, can I simply weight them 2x, or 3x respectively?
is it simply that what is meant?? or how does it work? I remember that in the MetaCost operator, the meaning of the weights is somewhat different if I'm correct...
