feasible direction meaning in Chinese
可行方向
Examples
- An feasible direction algorithm for solving generalized semi - infinite programming
广义半无限规划问题的一种可行方向算法 - On one hand , systems of nonlinear inequalities appear largely in practical application fields . on the other hand , the problem is the methods of feasible directions need to be solved
非线性不等式组不仅在实际问题中有广泛的应用，而且它也是最优化方向的可行方向类算法需要解决的问题。 - In every iteration only a sub - optimization is solved . decomposition and optimization technology based on feasible direction provide a feasible method to solve the support vector machines " training problem
分解与基于可行方向的优化技术结合为解决大数据集的支持向量机训练提供了一种可行的方法。 - Such methods are generally decreasing method , such as , feasible direction methods , constrained variable metric methods , etc . another class is sub - problems method , which approximates the optimal solution by solving a series of simple sub - problems , such as penalty function methods , trust region methods , and successive quadratic programming sub - problems , etc . the same property of two classes of methods is that they determine whether the next iterative point is " good " or " bad " by comparing the objective function value or merit function value at the current point and next iterative point
另一类叫做子问题算法，这种算法是通过一系列简单子问题的解来逼近原问题的最优解，如罚函数法、信赖域算法、逐步二次规划算法等。这两类算法的一个共同特点是，通过比较当前点和下一个迭代点的目标函数值或评价函数值来确定迭代点的“优”或“劣” ，若迭代点比当前点“优”则该迭代点可以被接受，否则须继续搜索或调整子问题。 - The heuristic analysis , some concepts and theorems of constrained optimization are employed , e . g . , linear feasible direction ( lfd ) , and then the proof is first provided for the uniqueness , i . e . , maximum nongaussianity is the sufficient and necessary condition to independent source recovery . moreover , based on the conclusion of the uniqueness of maximum nongaussianity , the paper also proposes an alternative but straightforward approach to the proof for the well known “ one - bit - matching ” conjecture presented in multi - unit approaches
和基于启发性分析等传统方法和结论比较,文中引入了线性化可行方向( linearfeasibledirection , lfd )等约束优化概念和理论,首次给出了基于峭度的最大非高斯估计的唯一性证明,指出最大非高斯估计是独立源提取的充分和必要条件。
