Estimating Global Input Relevance and Enforcing Sparse Representations with a Scalable Spectral Neural Network Approach

arXiv — cs.LGMonday, November 24, 2025 at 5:00:00 AM
  • A novel method has been proposed to estimate the relevance of input features in Deep Neural Networks by utilizing a spectral re-parametrization of the optimization process. This approach ranks input components based on their eigenvalues, providing a robust measure of their importance during network training without requiring additional processing.
  • This development enhances the explainability of machine learning models by enforcing sparse representations, allowing for the identification of a minimal subset of input features that contribute significantly to decision-making processes.
  • The implications of this research extend to various applications in artificial intelligence, including improving the interpretability of models in areas like side-channel analysis and visual emotion recognition, where understanding the relevance of input features is crucial for effective performance.
