Large-scale empirical tuning and comparison of default optimizers for variational inference

arXiv:2606.07841v1 Announce Type: cross Abstract: Black-box variational inference (BBVI) is a methodology for posterior approximation that relies on stochastic optimization. In practice, the stochastic optimizers underpinning BBVI generally require extensive problem-specific tuning, which undermines its promise as a truly "black box" inference algorithm. However, over the past decade, many new adaptive stochastic optimization algorithms have been developed that reduce or remove entirely the need for tuning. In this work, we investigate this new collection of adaptive methods in the context of

Why this matters
Why now

The proliferation of complex AI models necessitates more efficient and less resource-intensive optimization techniques, driving research into adaptive methods for variational inference.

Why it’s important

Improved variational inference optimizers can significantly reduce the computational burden and expertise required for training advanced AI models, democratizing their development and deployment.

What changes

The reliance on extensive problem-specific tuning for stochastic optimizers in black-box variational inference will decrease, making AI model development more accessible and scalable.
