Unconstrained svm
Web9 Apr 2024 · The goal of SVM is to find the hyperplane that maximizes the margin between the data ... This involves transforming the original problem into an unconstrained optimization problem using an ... WebThe SVM training problem can be equivalently formulated as a (linearly constrained) quadratic convex problem or, by Wolfe’s duality theory, as a quadratic convex problem with one linear constraint and box constraints. Depending on the formulation, several optimization algorithms have been specifically designed for SVM training.

There is one simple way to find the global minimum: 1. Find all the local minima 2. Take the smallest one; it is the global minimum. Another approach is to study the function we are trying to minimize. If this function is convex, then we are sure its local minimum is a global minimum.
