AMA
Inspired by Prof. Wei-Chiu Ma and Prof. Kyunghyun Cho’s pro bono sessions, I welcome anyone to reach out and ask me questions. You can email me with specific questions about AI, mathematics, philosophy, work, study, PhD applications, life, or anything else. I may not have definitive answers, but I am happy to share what I have seen and learned.
One small note: I do not consider myself senior or particularly successful, so I call this an AMA rather than a pro bono session. I simply hope to offer another perspective. Unlike many people in similar spaces, I completed my undergraduate studies in mainland China and later joined ByteDance Seed in Beijing. I did apply for PhD programs, but could not obtain a visa in the end. If you are looking for more professional guidance, I encourage you to also reach out to others who may be better suited to help.
