Bio
My research is in the area of machine learning, and includes contributions in the areas of artificial intelligence in education and educational data mining. I have published 80+ papers in highly ranked conference proceedings and my applied research has resulted in 40+ technology transfer and patents.
I conduct reproducible research. Trained models, datasets and scripts of data preprocessing and model training can be found at pykt.org, ai4ed@GitHub, tal-ai@GitHub, and tal-tech@GitHub.
Before joining JNU, I was the CTO of ThinkAcademy, CTO of Xueersi 1 on 1 and Head of AI Lab at TAL Education Group (NYSE: TAL).
