σC(y)=maxx∈C⟨y,x⟩ 通俗来说是集合C的y法向切平面最大截距(集合的闭凸包可以由集合的超平面包络得到) 支撑函数是次线性函数 次梯度和次微分 f(y)≥f(x)+⟨g,y−x⟩,∀y∈E(次梯度) ∂f(x)={g∈E∗:f(y)≥f(x)+⟨g,y−x⟩,∀y∈E}(次微分是次梯度的集合) ...
故,(x_n,\alpha) \in epif,又因为f是闭函数,因此epif是闭集,设x_n \rightarrow \bar{x}(n\rightarrow \infty),因此可得:(x,\alpha) \in epif,即f(x) \le \alpha,故x \in Lev(f,\alpha),因此命题(Ⅲ)成立。 (Ⅲ)\Rightarrow(Ⅰ):利用反证法:即假设命题(Ⅲ)成立时,命题(Ⅰ)不成立。则f...

对偶空间与双重对偶空间:向量空间上的线性泛函构成对偶空间,用符号表示。给定向量空间,其内积与对偶空间内积保持一致。对偶范数定义为线性泛函在单位球面上的最大内积值。引理证明了广义不等式成立。在有限维空间,双重对偶空间与原始空间同构,双重对偶范数与原始空间范数一致。伴随变换定义:给定向量空间与...
Runge-Kutta methodsScaling and preconditioning techniquesIt is well known that there is a strong connection between time integration and convex optimization. In this work, inspired by the equivalence between the forward Euler scheme and the gradient descent method, we broaden our analysis to the ...
In this talk, we will present first-order methods for solving a class of bilevel optimization problems using either single or sequential minimax optimization schemes. We will discuss the first-order operation complexity of these...
