Stability of Measure-to-Measure Transformers on Sub-Gaussian Data

This paper provides a mathematical analysis of measure-to-measure transformers, showing that they map sub‑Gaussian inputs to sub‑Gaussian outputs and are Hölder continuous with respect to the 1‑Wasserstein distance on suitable spaces. It establishes error‑propagation estimates for transformers applied to empirical approximations of sub‑Gaussian data and investigates a mean‑field analogue of cross‑attention, revealing distinct Hölder regularity and sample‑complexity for its two inputs. The results culminate in approximation guarantees for measure‑to‑measure transformers, offering a rigorous stability and finite‑sample theory for transformers on sub‑Gaussian data.
