强压缩映射与拓扑非凸优化
Strong contraction mapping and topological non-convex optimization
摘要:
强压缩映射是值域始终是定义域的子集的自映射,它存在唯一的不动点,该不动点可以通过映射的迭代来确定。我们引入一个拓扑非凸优化方法,作为强压缩映射的应用,以实现全局极小值收敛。该方法的优点是对局部极小值和初始点位置的鲁棒性。
英文摘要:
The strong contraction mapping, a self-mapping that the range is always a subset of the domain, admits a unique fixed-point which can be pinned down by the iteration of the mapping. We introduce a topological non-convex optimization method as an application of strong contraction mapping to achieve global minimum convergence. The strength of the approach is its robustness to local minima and initial point position.
