Eduction

PhD in Machine Learning, at INRIA
PostDoc at MIT CSAIL

I'm Hongzhou, currently being an Applied Scientist at Amazon. I am actively involved in projects related to supply chain management, price modeling and LLM (Large Language Model) applications.

Before my journey at Amazon, I dedicated myself to research in optimization algorithms, diving into the theoretical aspects of deep learning and reinforcement learning. My postdoctoral work was conducted in the Machine Learning Group at MIT under the guidance of Stefanie Jegelka, offering a rich environment for advanced study and innovation.

My academic roots trace back to INRIA Grenoble, where I completed my PhD in November 2017. Under the mentorship of Zaid Harchaoui and Julien Mairal, I focused my thesis on developing generic acceleration scheme on first-order optimization algorithms. This work laid a foundational stone for my subsequent endeavors in the world of applied science and technology.

Who is

RedPig

RedPig picture

After years of dedicated training in Maths Olympiads, I earned a silver medal in CMO (China National Olympiad) during my 10th grade. This was the peak moment of my competition career and something I'm very proud of.

A few years later, I find myself still in love of problem solving. That's when I start to build a Youtube Channel on Maths Olympiad and my name is RedPig! You can find my youtube channel here

Now, as a retired contestant, I continue to contribute to the USA Maths Olympiads cycle, involving myself in everything from problem proposing to grading. Additionally, I offer my expertise as an independent coach. If you're interested in taking lessons and enhancing your skills in Maths Olympiad, please feel free to reach out to me.
