Any-Dimensional Learning by Sampling

arXiv:2607.07680v1 Announce Type: cross Abstract: Many machine learning models are defined for inputs of different sizes, such as point clouds containing different numbers of points, sequences of tokens of different lengths, and graphs on different numbers of nodes. Such models are trained on finitely-many examples of necessarily limited sizes. How well do these models generalize from inputs of small size to larger inputs of size not seen during training? Furthermore, evaluating such models on large inputs is often expensive. How can we sketch large inputs to obtain smaller ones on which the m

Why this matters
Why now

The paper addresses a fundamental challenge in machine learning related to generalization and efficiency across varying input sizes, which is becoming more critical as AI models are deployed in diverse real-world scenarios.

Why it’s important

This research could significantly improve the applicability and efficiency of AI models handling dynamic and large-scale data, impacting areas like autonomous agents, complex system simulations, and advanced data processing.

What changes

Current AI models often struggle with generalization to larger input sizes than those seen in training, and this research proposes a method to address this limitation, potentially leading to more robust and scalable AI.
