ABOUT WEI YUAN
Passionate about NLP, LLMs, and Generative AI, I specialize in building and validating AI solutions that push the boundaries of what\'s possible. Currently, as a Data Scientist in the AI/ML Model Validation team at TD Bank, I ensure cutting-edge ML models meet the highest standards for performance and reliability.With extensive experience in NLP, I’ve worked on everything from fine-tuning LLMs and designing Transformer-based models to developing advanced language models for conversational AI. My projects include optimizing job-matching algorithms with RAG models and building bilingual chatbots, resulting in measurable improvements in model accuracy and user satisfaction. I am also skilled in deploying models at scale, utilizing AWS, Docker, and CI/CD for streamlined workflows.
