Nonlinear Contractions on Semimetric Spaces

JAA, 1995
Abstract Let (X, d) be a Hausdorff semimetric (d need not satisfy the triangle inequality) and d–Cauchy complete space. Let ƒ be a selfmap on X, for which d(ƒx, ƒy) ≤ φ(d(x, y)), (x, y ∈ X), where φ is a non– decreasing function from R +, the nonnegative reals, into R + such that φn ...

Robustness Certification for Structured Prediction with General Inputs via Safe Region Modeling in the Semimetric Output Space

Proceedings of the 29th ACM SIGKDD Conference on Knowledge Discovery and Data Mining, 2023
Many real-world machine learning problems involve structured prediction beyond categorical labels. However, most existing robustness certification works are devoted to the classification case. It remains open for robustness certification for more general
