arXiv:2605.23156v1 Announce Type: new Abstract: Several machine learning models are defined for inputs of any size, such as graphs with different numbers of nodes and point clouds containing varying numbers of points. The universality properties of such any-dimensional models remain poorly understood, as universality is traditionally studied for models accepting inputs of a fixed size, defined on a compact subset of their domain. In sharp contrast, any-dimensional models can be viewed as sequences of functions defined on growing-sized inputs, and it is not clear in which sense they can be univ
The paper addresses a fundamental theoretical gap in machine learning's understanding of models designed for varying input sizes, a growing area of practical importance in AI development.
Improved theoretical understanding of any-dimensional universality can lead to more robust, generalizable, and universally applicable AI models, accelerating progress across diverse applications.
This research provides a foundational framework for analyzing the universality properties of AI models, which previously lacked rigorous theoretical grounding for inputs of varying sizes.
