Overview

Proposed method improves sample diversity in Bayesian neural networks, suggesting enhanced uncertainty estimation and performance.

Key Points

  • Enhanced sample diversity leads to improved uncertainty estimation in Bayesian Neural Networks (BNNs).
  • The proposed method allows faster mixing without increasing inference costs compared to standard SGMCMC.
  • Extensive experiments demonstrate superior performance in image classification tasks, particularly for out-of-distribution robustness.
  • A comparative study with Hamiltonian Monte Carlo shows the effectiveness of the new sampling approach.
