Variational bagging: a robust approach for Bayesian uncertainty quantification

arXiv — stat.MLWednesday, November 26, 2025 at 5:00:00 AM
  • A new approach called variational bagging has been introduced, integrating a bagging procedure with variational Bayes methods to enhance Bayesian uncertainty quantification. This method aims to improve inference by addressing the limitations of traditional mean-field variational families, which often underestimate uncertainty and fail to capture parameter dependence.
  • The significance of this development lies in its potential to provide more accurate uncertainty quantification in various applications, particularly in fields relying on deep learning and complex statistical models. By establishing strong theoretical guarantees, this method could enhance the reliability of Bayesian inference in practical scenarios.
  • This advancement reflects a broader trend in machine learning and statistical modeling towards improving uncertainty quantification and model robustness. As researchers explore various methodologies, including generative models and deep neural networks, the integration of techniques like variational bagging highlights the ongoing evolution of approaches aimed at addressing the complexities of high-dimensional data.
