1)saddle point problem鞍点问题 1.Then we concentrate on the construction of the discrete space of Lagrange multiplier, the space of mortar elements, and the conjugated gradient method for the related saddle point problem.接着重点讨论了Lagrange乘子的近似空间 ,即粘接元 (mortarelements)空间的建立 ,以...
Identifying and attacking the saddle point problem in high-dimensional non-convex optimization Yann N. Dauphin 许多科学和工程领域面临的一个核心挑战是最小化连续高维空间中的非凸误差函数。梯度下降或拟牛顿法几乎普遍用于执行此类最小化,人们通常认为,这些局部方法难以找到全局最小值的主要原因是局部最小值的扩...

We impose the following conditions on the saddle point problem (1.1). (A1) F = ∂ϕ is the subdifferential of a proper, lower semi–continuous, strictly convex functional ϕ : R n → R = R ∪ {∞}. The inverse F −1 : R n → R n is single-valued and Lipschitz contin...

If we cannot solve the saddle-point problem directly, in many applications, we have to use some iterative method. Coupled iterative methods applied to the system ( 1.1) take some initial guess Open image in new window and generate approximate solutions Open image in new window for k = 1, ...
We consider problems where D = 0 or [parallel]D[parallel] is small, so that our problems retain the character of a (generalized) saddle-point problem. In addition, certain finite element stabilization schemes yield B [not equal to] C [1, 22] and [24, Sections 7.5 and 9.4], while ...
This paper studies the saddle point problem of polynomials. We give an algorithm for computing saddle points. It is based on solving Lasserre’s hiera
到2014年,一篇论文《Identifying and attacking the saddle point problem in high-dimensional non-convex optimization》(https://arxiv.org/pdf/1406.2572v1.pdf)。 指出高维优化问题中根本没有那么多局部极值。作者依据统计物理,随机矩阵理论和神经网络理论的分析,以及一些经验分析提出高维非凸优化问题...
