邻近点映射的性质下面这个定理讨论了邻近点映射和次梯度的关系 定理:假设 f:\mathbb{E}\to [-\infty,\infty] 是一个合理(proper:函数不恒等于正无穷且不取负无穷值)闭凸函数,那么以下三个命题是等价的( x,y…
first-order methods in optimization First-order methods are an important class of algorithms for convex and non-convex optimization. They are numerical schemes for minimizing the objective function, usually involving only the function value and its gradient or some approximation thereof at each ...
First-order methods in optimization. The author of First-order methods in optimization defines the book's subject matter as optimization methods that rely on function \"values and gradients/subgradients (but not Hessians).\" The most familiar example of a first-order method... C Jones - 《...

comprehensive study of the main first-order methods that are frequently used in solving large-scale problems. First-order methods exploit information on values and gradients/subgradients (but not Hessians) of the functions composing the model under consideration. With the increase in the number of...
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...
