Enhancing Generative Auto-bidding with Offline Reward Evaluation and Policy Search

arXiv:2509.15927v5 Announce Type: replace Abstract: Auto-bidding is a critical tool for advertisers to improve advertising performance. Recent progress has demonstrated that AI-Generated Bidding (AIGB), which learns a conditional generative planner from offline data, achieves superior performance compared to typical offline reinforcement learning (RL)-based auto-bidding methods. However, existing AIGB methods still face a performance bottleneck due to their inherent inability to explore beyond the static dataset with feedback. To address this, we propose \textbf{AIGB-Pearl} (\emph{\textbf{P}la

Why this matters
Why now

The paper addresses the current bottleneck of AI-generated bidding models, which are limited by static offline data, and proposes an advancement that integrates offline reward evaluation and policy search for improved performance.

Why it’s important

This research introduces a method to overcome a significant limitation in AI-driven advertising, potentially leading to more efficient ad spending and higher returns for advertisers.

What changes

Existing AI-generated bidding systems, which previously struggled with exploring beyond static datasets, can now incorporate dynamic learning from offline reward evaluations and policy searches, making them more adaptable and effective.

Winners
  • · Digital advertising platforms
  • · Advertisers
  • · E-commerce companies
Losers
  • · Advertisers not adopting advanced AI bidding
Second-order effects
Direct
