Biography

I’m Danrui Qi, a 5th-year Ph.D. candidate at Simon Fraser University under the supervision of Prof. Jiannan Wang. I also work closely with Prof. Zhengjie Miao. My research interests mainly focus on good data for AI and AI for good data, which include:

  • Automated data preparation, with a specific focus on self-envolving data science agent and the automatic augmentation of features for complex relational tables.
  • Large Language Model reasoning on table tasks, e.g. Text-to-SQL and TableQA.
  • Automated Machine Learning (AutoML), especially automating the feature preprocessing part in the AutoML workflow.
  • The application of Bayesian Optimization and Reinforcement Learning techniques in the realm of Data Preparation.

Recently, I’m also very interested in Business Intelligence powered by Large Language Models (LLMs).

Collaboration & Mentoring

I welcome discussions on Automated Data Science & AI agents and am open to collaborations with researchers and industry professionals. I also enjoy mentoring students at various stages of their academic journey.

If you’re interested in exploring potential collaborations or discussing recent developments in the field, feel free to schedule a conversation here.
