Multiplicative Reweighting for Robust Neural Network Optimization

arXiv — cs.LGWednesday, November 12, 2025 at 5:00:00 AM
The introduction of Multiplicative Reweighting (MW) for neural network optimization addresses a critical challenge: the degradation of model performance due to noisy labels during training. By leveraging principles from learning with expert advice, MW updates have been theoretically established to converge when used with gradient descent, proving advantageous in one-dimensional cases. Empirical validation on datasets such as CIFAR-10, CIFAR-100, and Clothing1M reveals that MW significantly enhances the accuracy of neural networks in the presence of label noise. Furthermore, the method shows promise in improving adversarial robustness, which is increasingly vital in the context of machine learning applications facing real-world data challenges. This advancement not only contributes to the field of artificial intelligence but also sets a foundation for more resilient neural network architectures in various applications.

NeutralArtificial Intelligence
The article explores the approximation and learning capabilities of neural networks in relation to their VC dimension, focusing on high-dimensional geometry and statistical learning theory. It highlights that while a finite VC dimension is beneficial for uniform convergence of empirical errors, it may not be ideal for approximating functions from a probability distribution relevant to specific applications. The study demonstrates that errors in approximation and empirical errors behave almost deterministically for networks with finite VC dimensions when processing large datasets.
