Optimizing Neural Network Performance and Interpretability with Diophantine Equation Encoding

Ronald Katende

TL;DR

This work tackles the interpretability and robustness gap in neural networks by encoding parameters as integer solutions to Diophantine constraints. It introduces a framework that maps real-valued parameters to integer representations under a polynomial constraint $P(x_1, ..., x_n) = 0$ and augments training with a Diophantine penalty, implemented within common deep learning libraries. Theoretical results establish existence and (in a restricted sense) uniqueness of the encoding, along with convergence and generalization benefits from Diophantine regularization and activation-function designs, supported by mechanisms like adversarial-perturbation constraints. Empirical evaluations on image classification and natural language processing tasks demonstrate competitive accuracy, enhanced adversarial robustness, and improved interpretability, indicating practical benefits for resource-constrained and safety-critical applications.

Abstract

This paper explores the integration of Diophantine equations into neural network (NN) architectures to improve model interpretability, stability, and efficiency. By encoding and decoding neural network parameters as integer solutions to Diophantine equations, we introduce a novel approach that enhances both the precision and robustness of deep learning models. Our method integrates a custom loss function that enforces Diophantine constraints during training, leading to better generalization, reduced error bounds, and enhanced resilience against adversarial attacks. We demonstrate the efficacy of this approach through several tasks, including image classification and natural language processing, where improvements in accuracy, convergence, and robustness are observed. This study offers a new perspective on combining mathematical theory and machine learning to create more interpretable and efficient models.

Theorem 1

For any neural network parameter set $\theta = \{W, b\}$, there exists a Diophantine equation $P(x_1, x_2, \ldots, x_n) = 0$ such that its solution $(x_1, x_2, \ldots, x_n)$ maps to $\theta$ via a unique function $\Phi: \mathbb{R}^m \rightarrow \mathbb{Z}^n$.
