Hi,
保持变化，保持探索，保持思考。
I am an undergraduate in Data Science and Big Data Technology at Chongqing University, originally from Danyang, Jiangsu.
My interests currently sit around Natural Language Processing, Large Language Models, Model Behavior & Evaluation, and Reliable AI Systems.
I want to pair research judgment with the ability to build: choosing worthwhile questions, then testing them carefully in research and code. I am always happy to connect.
