WebMajorization-Minimization Consider the following presumably diﬀicult optimization problem: minimize x f(x) subject to x ∈X, with Xbeing the feasible set and f(x) being continuous. Idea: successively minimize a more managable surrogate function u(x,xk): xk+1 = argmin x∈X u(x,xk), hoping the sequence of minimizers {xk}will converge to optimal x⋆. Question: … Web2.

WebMany examples of Schur convex functions can of course be found in the literature. Perhaps the sim-plest example is what is called a separable convex function. It is of the form g(x)= Xn i=1 h(xi), where h is a convex function. We now begin our tour of examples in the liter-ature in which majorization makes cameo and/or starring appearances. WebThe function ϕ(t) = log(1 +t/ε), for t ≥0, is concave and is majorized at t = t0 by its linearization: ϕ(t) ≤ϕ(t0)+ϕ(t0)′(t −t0) = ϕ(t0)+ 1 ε+t0 (t −t0) Thus, the function ϕ( xi ) is … prof. dr. michaela geierhosWebmajorization-minimization point of view, such as DC programming [8], where “DC” stands for dif-ference of convex functions, variational Bayes techniques [28], or proximal … prof. dr. med. ulrich wolters
