Evidence-Gated Research: Statistically Controlled Model Adoption in Adaptive Search

The paper introduces Evidence‑Gated Research (EGR), a statistical adoption layer designed for adaptive model search where each new challenger is frozen until evidence is revealed. EGR constructs anytime‑valid evidence across predefined environments, routes it toward unresolved components, composes a persistent candidate e‑value, and forwards this to an online controller. The method guarantees false discovery rate control for the declared all‑environment adoption target, even when earlier adoptions influence later challengers, and demonstrates evidence efficiency and persistent FDR control in large‑scale benchmarks.

Offline Policy Evaluation as a decision support tool for designing Adaptive Experiments

The paper explores how data from fixed A/B tests can guide the deployment of adaptive experiments using contextual bandits. By combining off‑policy evaluation with a controlled warm‑start simulation, the authors rank pre‑specified adaptive and non‑adaptive policies using doubly robust estimators. Experiments on synthetic trials and real benchmarks show that adaptive, context‑aware policies outperform fixed allocations when heterogeneity exists, but offer little advantage otherwise.

A-SR: Self-Evolving Agentic LLMs for Symbolic Regression via Hierarchical Coordination

arXiv:2608. 04872v1 Announce Type: cross Abstract: Symbolic regression aims to discover closed-form equations from data, but existing LLM-guided methods often rely on a unified proposal loop that compresses heterogeneous search failures into a scalar score and a single prompt.
