RECOMMENDER SYSTEMS & GENERATIVE AI
Action-Aware Generative Sequence Modeling for Short Video Recommendation
Traditional recommendation models struggle with the nuanced and dynamic nature of user preferences in short video platforms. By treating videos as holistic units, they often fail to capture diverse user intentions across segments, leading to suboptimal recommendations. Our Action-Aware Generative Sequence Network (A²Gen) addresses this by modeling user actions along a temporal dimension, enabling precise, segment-level interest capture and dramatically improving recommendation accuracy and user engagement.
Executive Impact: Unlocking Engagement & Retention
A²Gen's deployment on a leading short video platform demonstrates significant, measurable improvements across critical business metrics, translating directly into enhanced user value and revenue growth.

Benchmarking Against State-of-the-Art Models
Offline experiments on Kuaishou and Tmall datasets showcase A²Gen's superior prediction capabilities across various user actions and timing estimations.
Offline Evaluation: Significant Accuracy Gains
Our A²Gen model demonstrated superior performance in offline experiments on both Kuaishou's and Tmall's datasets. It achieved significant AUC improvements across all action types, including a 58 basis point improvement in Like action prediction over the SOTA HOME model and a 143 basis point improvement over the online production model PLE. Furthermore, A²Gen showed lower MAE loss for timing predictions, with a 2.60% reduction in Like timing loss compared to HOME. These results confirm A²Gen's ability to capture richer latent patterns and translate them into superior prediction accuracy.
Real-World Impact & Production Deployment
A²Gen has been successfully deployed, demonstrating its robustness and significant positive impact on user experience and key business metrics.
