Uncertainty-Preserving QBNNs: Multi-Level Quantization of SVI-Based Bayesian Neural Networks for Image Classification

arXiv — cs.LGFriday, December 12, 2025 at 5:00:00 AM
  • A new framework for multi-level quantization of Stochastic Variational Inference-based Bayesian Neural Networks (BNNs) has been introduced, addressing the computational and memory overhead associated with traditional BNNs. This framework employs three distinct quantization strategies: Variational Parameter Quantization, Sampled Parameter Quantization, and Joint Quantization, allowing BNNs to maintain performance even at reduced precision levels, as demonstrated through experiments on the Dirty-MNIST dataset.
  • The development of this quantization framework is significant as it enables the practical deployment of Bayesian Neural Networks in resource-constrained environments, enhancing their applicability in real-time applications such as image classification. By achieving quantization down to 4-bit precision while preserving uncertainty estimation, this work opens new avenues for integrating BNNs into various technological domains.
  • The advancement in quantization techniques for BNNs reflects a growing trend in artificial intelligence towards improving efficiency without sacrificing performance. This aligns with ongoing efforts in the field to better manage uncertainties in machine learning models, as seen in applications ranging from structural health monitoring to digital image correlation. The focus on uncertainty quantification is crucial as industries increasingly rely on AI for critical decision-making processes.

Unreliable Uncertainty Estimates with Monte Carlo Dropout
NegativeArtificial Intelligence
A recent study has highlighted the limitations of Monte Carlo dropout (MCD) in providing reliable uncertainty estimates for machine learning models, particularly in safety-critical applications. The research indicates that MCD fails to accurately capture true uncertainty, especially in extrapolation and interpolation scenarios, compared to Bayesian models like Gaussian Processes and Bayesian Neural Networks.
