👋Yile Li(李怡乐)

Welcome! This is Yile Li 👧, an undergraduate majoring in Cyberspace Security at Communication University of China.

I am broadly interested in information retrieval and information security. My current research focuses on recommendation system, specifically bundle generation.

Outside of coding, I enjoy 🎸playing the guitar, 🎶exploring different genres of music, and staying active with 🏸badminton and 🏊swimming.

Currently seeking opportunities to pursue a master's degree, I'm always ready to tackle new challenges!

Experience

Large Language Model for Bundle Generation

Aug 2023 - Present | Multimedia Computing Laboratory Academic Training Season

Developed a deep and comprehensive understanding of foundational deep learning techniques through theoretical study and extensive model reproduction.

Conducted a comprehensive literature review on state-of-the-art recommender systems, focusing on bundle generation methods. Selected and replicated baseline models to ensure a solid foundation for further research.

Developed a bundle generation pipeline that integrates GNN's structural-awareness with LLM-enhanced data embeddings to incorporate open-world knowledge, using noise-based training to improve robustness and reduce the impact of low-quality data. Currently refining the model for enhanced performance.
