WebDual coefficients of the support vector in the decision function (see Mathematical formulation), multiplied by their targets. For multiclass, coefficient for all 1-vs-1 … WebSVM decision function h(z) = sign Xn i=1 y iα ik(x i,z) + b! Kernel SVM is like a smart nearest neighbor: it considers all training points but kernel function assigns more weight to closer points. It also learns a weight α i >0 for each training point and a bias b, and sets many α i = 0 for useless training points.
