Function-Counting Theory for Low-Dimensional Data Structures

arXiv:2607.01010v1 Announce Type: cross Abstract: The success of deep learning models in classification and regression is widely attributed to the low-dimensional structure that real-world data tend to exhibit, despite their high-dimensional representation. This work attempts to provide a mathematical framework for binary classification on low-dimensional data, building on Cover's (1965) function-counting theory. With our framework, we aim to address the question of how the low-dimensional structure of the data affects the classification capabilities of learning models. Cover's theory relies o

Why this matters
Why now

This research builds on a foundational theory from 1965, indicating a renewed focus on theoretical underpinnings as AI models become more complex and their limitations in real-world scenarios gain attention.

Why it’s important

Understanding the mathematical framework for how low-dimensional data structures impact classification capabilities could lead to more efficient, robust, and interpretable AI models, particularly in data-constrained or sensitive applications.
