Acknowledgements

I would like to express my sincere gratitude to the people who have supported and shaped my academic journey.

Prof. Yan Jin · Reinforcement Learning & Intelligent Computing Group, HUST

I am deeply grateful to Prof. Jin for believing in me, providing invaluable research opportunities, and offering continuous guidance throughout my undergraduate years. Her recognition and mentorship have been instrumental in my growth as a researcher, and I have no doubt that her support played a significant role in my admission to Imperial College London.

JD.com

I would like to thank JD.com for the opportunities across two chapters of my journey. During my first internship (2025.03 - 2025.08), I had the most wonderful time working alongside a talented and dedicated team, an experience I truly cherished and one that I believe played no small part in opening the doors that followed. I am also deeply grateful for the trust placed in me as I return this summer as a Machine Learning Engineer, an opportunity I look forward to with great excitement.

I feel truly fortunate to have had such wonderful mentors and opportunities, and I look forward to making the most of what lies ahead.
