AI 摘要
Pinterest 在 arXiv 发布其生产级动态创意优化系统 PinDCO，用于十亿级视觉发现平台上的广告创意检索与选择。系统核心为 Creative Component Fusion Network（CCFN），对图像、标题、布局等创意组件分别建模并融合打分，同时引入 Pixel-aware Adjustment Module（PAM）根据创意尺寸调整分数，以适配瀑布流布局并优化整页效果。为应对生成式 AI 带来的候选创意激增，PinDCO 采用轻量预选模型提前剪枝，并通过缓存和动态批处理优化服务效率。离线分析与线上 A/B 实验显示其提升了广告点击率且整页指标为正，已在 Pinterest 广告平台上线。

by PinDCO: Whole-Page Aware Dynamic Creative Optimization at Scale Abstract. Recent advances in generative AI have substantially accelerated the creation of high-quality ad creatives, dramatically expanding the number of candidate variants per campaign. This shift increases the need for scalable dynamic creative optimization (DCO) systems that can match creatives to the most relevant audiences under stringent latency and cost constraints. We present PinDCO, a production DCO system for ad creativ
