Position: The Time for Sampling Is Now! Charting a New Course for Bayesian Deep Learning

arXiv:2605.21765v1 Announce Type: new Abstract: The practical adoption of sampling-based inference (SAI) in Bayesian neural networks (BNNs) remains limited, partly due to persistent misconceptions about the feasibility and efficiency of sampling. This position paper argues that SAI has achieved computational parity with optimization-based methods and is at the verge of superseding such methods for effective and efficient inference in BNNs. This development should be in the interest of the whole community, promoting BNNs as a principled paradigm with its long-standing yet unfulfilled promise of

Why this matters
Why now

The paper suggests that recent advancements have brought sampling-based inference to computational parity with optimization methods, challenging longstanding assumptions about its practicality in Bayesian deep learning.

Why it’s important

This development could significantly enhance the robustness and reliability of AI models, addressing critical limitations in current deep learning paradigms and enabling more principled approaches.

What changes

The perceived limitations of sampling-based inference in Bayesian neural networks are being reassessed, potentially shifting the focus towards more effective and efficient inference methods.
