I am currently an Applied Scientist at Amazon, working on search, ranking, pricing, and LLM problems. Before that, I was a post-doc and received my Ph.D. in the Computer Science Department at Purdue University, working on research problems in optimization, machine learning, causal inference, and NLP. I received my B.S in the Computer Science Department at National Tsing Hua University and worked as a Research Assistant at Academia Sinica before moving to Purdue.

• Happy to announce that our paper on the Pricing Model was accepted in Amazon Machine Learning Conference (AMLC) Pricing Workshop, Oct 2024. ( We showed that via pretraining from multiple distributions of samples, the pricing model can reach flatter minima, via measuring the flatness of multimillion parameters loss landscape using constrained LBFGS , which means better generalization, and most importantly, setting/recommend the price of a product more accurately :) )
