What is duality in SVM?

What is duality in SVM?

In mathematical optimization theory, duality means that optimization problems may be viewed from either of two perspectives, the primal problem or the dual problem (the duality principle). The solution to the dual problem provides a lower bound to the solution of the primal (minimization) problem. (

Is SVM convex optimization?

So the SVM constraints are actually linear in the unknowns. Now any linear constraint defines a convex set and a set of simultaneous linear constraints defines the intersection of convex sets, so it is also a convex set.

Is SVM optimal?

Support Vector Machine. There are numerous hyperplanes which can separate the two-class data but SVM produces the optimal hyperplane as indicated in Figure 2. This hyperplane has the maximum distance to support vectors. The margin of a separating hyperplane is .

Which is the best way to solve SVM optimization?

Recall that the SVM optimization is as follows: Here is the overall idea of solving SVM optimization: for the Lagrangian of SVM optimization (with linear constraints), it satisfies all the KKT Conditions. Therefore, we can solve it by solving its dual problem, and the dual problem has some nice properties that allows us to use Kernel trick.

What does duality mean in support vector machine?

If you did not read the previous articles, you might want to start the serie at the beginning by reading this article: an overview of Support Vector Machine. In mathematical optimization theory, duality means that optimization problems may be viewed from either of two perspectives, the primal problem or the dual problem ( the duality principle ).

How is the duality principle used in optimization theory?

In mathematical optimization theory, duality means that optimization problems may be viewed from either of two perspectives, the primal problem or the dual problem (the duality principle). The solution to the dual problem provides a lower bound to the solution of the primal (minimization) problem.
