AdsWorldEngine introduces a self‑evolving framework composed of an Opportunity Gate, an Orchestrator, a tool‑coefficient loop, and an Evaluator to achieve this end‑to‑end process. The core innovation is the iterative actor‑tool training that simultaneously improves both the conversational agent and its advertising tools using reward‑driven preference data. ## Key Contributions - [Finding 1] A unified agentic pipeline—Opportunity Gate, Orchestrator, tool co‑evolution, and Evaluator—that autonomously decides ad relevance and constructs top‑3 ads. - [Finding 2] An iterative actor‑tool training loop that leverages high‑ and low‑reward rollouts to generate preference data for tool refinement, enabling self‑improving advertising capabilities. - [Finding 3] A label‑grounded judgment model trained from human labels enriched with thinking traces, filtered via reflection, and optimized with a cost‑sensitive GRPO variant that preserves asymmetric reward gaps. ## Methodology The authors first train the Orchestrator using supervised fine‑tuning combined with agentic reinforcement learning to generate commercial intents and select appropriate advertising tools. They then execute high‑reward and low‑reward rollouts, collecting preference data that is used to iteratively update the tool models. To handle subjective production decisions, they employ a judgment model trained on human labels collected under explicit guidelines; this model’s outputs are refined through reflection to eliminate inconsistent rationales and further optimized with GRPO to maintain reward asymmetry. ## Results Offline evaluation shows that AdsWorldEngine improves ad diversity by 60% and relevance by 80% compared with the current production system. In an online A/B test, it lifts RPM by 22% and increases ads coverage by 74%, demonstrating tangible gains in both efficiency and user exposure. ## Significance By integrating self‑evolving tools within a conversational advertising agent, AdsWorldEngine addresses the dual challenge of relevance and intrusiveness that plagues existing ad delivery systems. The framework not only boosts commercial performance but also advances research on adaptive AI agents capable of continuous improvement through reward‑driven learning. ## Related Concepts - Conversational Advertising - Opportunity Gate (ad decision logic) - Orchestrator (intent generation & tool selection) - Tool Coevolution (iterative model updating) - Evaluator (offline optimization of ad relevance) - Label‑Grounded Judgment Modeling - GRPO (Generalized Policy Optimization) with cost sensitivity
