Recommendation Large Model Researcher-Global E-commerce

tly better performance than current baseline models, and applying them across multiple business scenarios such as Douyin short videos/LIVE/E-commerce/Toutiao. Developing large models for recommendation is particularly challenging due to the high demands on engineering efficiency and the personalized nature of user recommendation experiences. The project will conduct in-depth research across the following directions to explore and establish large model solutions for recommendation scenarios:
Project Challenges/Necessity:
The emergence of LLMs in the natural language field has outperformed SOTA models in numerous vertical tasks. In contrast, industrial-grade recommendation systems have seen limited major innovations in recent years. This project seeks to revolutionize the long-standing paradigms of recommendation model architectures and Infra in the recommendation field, delivering models with significantly improved performance and applying them to scenarios like Douyin short video and LIVE. Key challenges include:

High engineering efficiency requirements for recommendation systems;
Personalized nature of user recommendation experiences;
Effective content representation for media formats like short videos and live streams.
The project will address these through deep research in model parameter scaling, content/user representation learning, multimodal content understanding, ultra-long sequence modeling, and generative recommendation models, driving systematic upgrades to recommendation models.
Project Content:

1. Representation Learning Based on Content Understanding and User Behavior
2. Scaling of Recommendation Model Parameters and computing
3. Ultra-Long Sequence Modeling
4. Generative Recommendation Models
   Involved Research Directions: Recommendation Algorithms, Large Recommendation Models.
