Closing the Feedback Loop: From Experience Extraction to Insight Governance in Verbal Reinforcement Learning
Quick Answer
The paper introduces a three-layer architecture for verbal reinforcement learning that addresses the retention-forgetting dilemma in non-stationary environments.
Quick Take
By implementing a feedback-driven curation loop, the model enhances performance in financial forecasting, demonstrating that accumulated experience can either degrade or improve outcomes significantly based on governance. This approach emphasizes the need for structured evidence and compositional governance in agents.
Key Points
- Proposes a three-layer architecture: rules, evidence, and skills for LLM agents.
- Addresses retention-forgetting dilemma with outcome-driven evaluation and structured evidence.
- Demonstrates improved accuracy and risk-adjusted returns in financial forecasting.
- Existing methods focus on experience extraction but neglect insight governance.
- Curation loop crucial for leveraging accumulated experience effectively.

arXiv:2606. 17591v1 Announce Type: new Abstract: Training-free verbal reinforcement learning enables agents to learn from world feedback -- objective signals such as dynamic task outcomes, market returns, or demand forecasts -- by extracting verbal rules from experience and injecting them as context, updating the agent's behavior without parameter changes.
However, in non-stationary environments these agents face a retention-forgetting dilemma: retaining stale insights causes negative transfer, while discarding them causes catastrophic forgetting when conditions recur. …

HOBA (Hierarchical On-policy Bidding Agents) is a novel hierarchical reinforcement learning framework that enhances online advertising bidding systems by improving adaptability and reducing hyperparameter tuning costs. It utilizes a for hyperparameter inference, a SARSA agent for expert model selection, and a dynamic expert pool for bid execution, achieving a +3.6% increase in target cost during large-scale deployment and outperforming state-of-the-art baselines on AuctionNet.
