Hi, I'm Yifan He

MSc student in Computer Science (Artificial Intelligence) at the University of Nottingham.

What I focus on

  • LLM applications
  • Multimodal model evaluation
  • Dialogue systems
  • Prompt design and experiment analysis
  • Python-based AI prototyping

Selected Projects

  • Medical MLLM Evaluation and Model Selection
    Built a structured evaluation workflow for open-source multimodal LLMs in medical scenarios, comparing model quality and deployment-related costs.
  • Flight Booking Dialogue System
    Designed a task-oriented multi-turn dialogue system with intent recognition, state tracking, and error recovery.
  • Multi-Agent Cleaning System
    Implemented and compared Random, A*, Q-learning, and shared Q-learning agents in a grid-world environment.
  • Diabetes Multi-class Prediction
    Built and evaluated multi-class ML pipelines for health prediction with imbalanced data handling and result interpretation.

Tech Stack

Python, PyTorch, Scikit-learn, Transformers, Git, Tableau
