arXiv:2605.29908v1 Announce Type: cross Abstract: Sparse recovery in linear systems underpins applications from signal processing to high-dimensional regression. Sparse Bayesian Learning, grounded in the principle of automatic relevance determination (ARD), offers a practical Bayesian mechanism for feature sparsity via marginal likelihood optimization. Yet, its reliance on a homoscedastic noise model renders it sensitive to data contaminations such as outliers or misspecified noise, harming model fit and predictions. Instead, we propose jointly learning individual feature and sample relevancie
The continuous drive for more efficient and robust machine learning models, especially as AI scales, necessitates innovations in foundational techniques like sparse recovery.
Improving the robustness of sparse Bayesian learning to data imperfections could significantly enhance AI model performance and reliability in real-world, noisy datasets.
This research introduces a method for jointly optimizing feature and sample relevance, moving beyond the limitations of homoscedastic noise models in sparse recovery.
