YouRA: A Persistent-State Architecture for Evidence-Traceable Autonomous Research Agents

Read the original on arXiv AI →

YouRA (Your Research Agent) is a persistent-state architecture that enables evidence‑traceable autonomous research agents to maintain research state, execution evidence, and failure history across long‑horizon pipelines. It combines a Verification State Architecture to track hypotheses and evidence, an Independent Controller to manage lifecycle and recovery, and Stateful Reflection to log failures and guide repair. On the MLR‑Bench ten‑task subset, YouRA outperforms MLR‑Agent and AI Scientist V2, and ablation studies confirm the importance of each component.

Scores Alone Do Not Prove Discovery: The Discovery Certification Protocol for Auditing AI Research Agents

The paper introduces the Discovery Certification Protocol (DCP), a framework that transforms claims from AI research agents into executable tests for recovery and feedback. DCP includes multiple gates that validate improvements, provide controlled information, and measure the impact of truthful feedback, while its core requires strict controls and finite‑sample bounds. Controlled audits in SQLite optimization and virtual catalyst control demonstrated zero recoveries across 96 episodes, with rigorous verification by a deterministic, LLM‑free verifier.

EviGraph: Evidence-Guided Autonomous Research Agents

arXiv:2608. 04738v1 Announce Type: new Abstract: Autonomous research agents can generate hypotheses, execute experiments, and draft manuscripts, yet their outputs often contain unsupported claims and inconsistencies between research questions, experiments, results, and conclusions.

TruthInsightBench: An Evidence-Grounded Benchmark for Automated Evaluation of Open-Ended Scientific Discovery Agents

TruthInsightBench is a new benchmark designed to evaluate automated scientific discovery agents by presenting them with 40 blind tasks drawn from peer‑reviewed studies across ten domains. Each task provides only a neutral objective and frozen data, withholding source conclusions, expected values, and analysis paths, forcing agents to determine which claim the data support. A fixed LLM‑based judge scores agents on evidentiary maturity across six dimensions, using 29 artifact‑grounded items, enabling fully automated, repeatable evaluation without human grading.
