Weak contraction mapping and optimization

no code implementations ICLR 2019 Siwei Luo

The weak contraction mapping is a self mapping that the range is always a subset of the domain, which admits a unique fixed-point.

Strong contraction mapping and topological non-convex optimization

2 code implementations8 Jul 2018 Siwei Luo

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.
