Quadratic penalty function method
Did you know?
WebThe penalty function considered in original studies of multiplier methods was the quadratic ~(t) = ½t 2 which of course satisfies (Q). Since functions satisfying (Q) behave similarly as ~(t) = ½t 2 we refer to such penalty functions as essentially quadratic. WebPenalty, Logarithmic barrier methods • Penalty method • Logarithmic barrier method Goal: add to the original objective function an extra term that is zero when constraints hold and positive when constraints do not hold. Quadratic penalty φ = f(x)+ 1 2µ X i∈E c2 i with inequalities φ = f(x)+ 1 2µ X i∈E c2 i + 1 2µ X ∈i ([c i]−)2 ...
WebDec 17, 2024 · Support vector machine (SVM) models are usually trained by solving the dual of a quadratic programming, which is time consuming. Using the idea of penalty function method from optimization theory, this paper combines the objective function and the constraints in the dual, obtaining an unconstrained optimization problem, which could be … WebQuadratic penalty min x f(x) + ˙ k 2 kc(x)k2 2 Perturbs the solution.
