如果C中任意两点之间的线段在C中,则集合C是凸的(convex),即对于任意 x1,x2∈C 和任意 0≤θ≤1 的θ,我们有 θx1+(1−θ)x2∈C. 图2.2一些简单的凸集和非凸集(convex and nonconvex)。左边:六边形,包括它的边界(颜色较深),是凸的。中间。肾形kidney集合不是凸的,因为集合中以点表示的...

We propose two approaches based on the convex DEA and non-convex free disposable hull (FDH) approach with fuzzy variables. The purpose of this paper is two-fold: 1) we develop a CE analysis for non-parametric convex methods based on fuzzy set theory; 2) we further develop a non-convex ...
We consider the mixed regression problem with two components, under adversarial and stochastic noise. We give a convex optimization formulation that provably recovers the true solution, as well as a nonconvex formulation that works under more general settings and remains tractable. Upper bounds are pr...
where the relation ~ may be any combination of equal to, less than or equal to, greater than or equal to, or range constraints. As in other problem formulations, l indicates lower and u upper bounds. Q is a matrix of objective function coefficients. That is, the elements Qjjare the coe...
This also allows us to define an effective non-convex estimator where only one scalar variable is involved in the optimization process. Theoretical arguments, independent of the correctness of the priors entering the sparse model, are included to clarify the advantages of this non-convex technique ...
