arXiv:2608. 05642v1 Announce Type: new Abstract: This paper proposes the Bayesian Expected Uncertainty Reduction (B-EUR) model, which formalizes the value of trying a candidate design action as its expected reduction of epistemic uncertainty about action--outcome relations.

The paper introduces ACTION-BED, a Bayesian experimental design framework that replaces traditional uncertainty‑reduction objectives with expected future loss (EFL) on downstream actions. By reformulating EFLs into singly intractable objectives, ACTION-BED enables joint optimisation of design and action policies using stochastic gradients without explicit posterior or marginal likelihood estimation. This approach simplifies learning of design policies and allows easy customization to various downstream tasks and loss functions.

arXiv:2606. 19353v1 Announce Type: cross Abstract: In-Context Learning (ICL) allows LLMs to adapt to new tasks from a few demonstrations, but its reliability remains a concern: predictions are highly sensitive to both prompt design and the model's ability to understand the context, obscuring whether failures arise from data properties or model limitations.
