Duc-Anh Nguyen
Thank you for visiting! My name is Duc-Anh Nguyen. You can call me Duc Anh for short. Iβm an AI Research Resident at Qualcomm AI Research (formerly VinAI Research), advised by Dr. Toan Tran, Dr. Tung Pham, and Prof. Tan Nguyen.
Research Interest
My research focuses on uncovering the mathematical principles underlying foundation models, leveraging these insights to design efficient, interpretable, and robust LLMs and VLMs, with an emphasis on optimization, sparse modular architectures, and transfer learning.
