WebMar 28, 2015 · To this end we need to construct a vector from the plane to to project onto a vector perpendicular to the plane. Then we compute the length of the projection to determine the distance from the plane to the point. First, you have an affine hyperplane … WebThe distance between the hyperplane and its support vectors is called the margin. ... Eq. (9.19), and then check to see the sign of the result. This tells us on which side of the hyperplane the test tuple falls. ... The margin is the smallest distance between a data point and the separating hyperplane.

And there happens to be a problem about point's distance to hyperplane even for RBF kernel. First we know that SVM is to find an "optimal" w for a hyperplane wx + b = 0. And the fact is that. w = \sum_{i} \alpha_i \phi(x_i)

WebNov 16, 2024 · Particularizing to your data points a and b, we have that: f ( ϕ ( a)) = γ a ^ = 17 f ( ϕ ( b)) = γ b ^ = 9. Given this, we can conclude that only if the rest of the data points used to construct the hyperplane f ( ϕ ( x)) = 0 have bigger or equal functional margins, then b will be a support vector. Share.
