Seung Jun Choi
Welcome! I am a PhD student in Community and Regional Planning at The University of Texas at Austin. I conduct research in urban informatics with an emphasis on smart transportation, transportation equity, machine learning, and AI.
I currently serve as the Head Teaching Assistant in the Computer Science Department for a Master's course titled: 'Case Studies in Machine Learning' and as a Graduate Research Assistant in the Urban Information Lab. I have completed traineeship in the NSF: Ethical AI Portfolio program at UT Austin.
AICP-C·KEUP: I'm an AICP Candidate and also a certified planner in S. Korea

RESEARCH
My current projects evaluate the implications of smart transportation and AI to ensure fairness in pursuing public goods.
Path Towards Urban AI
My research focuses on optimizing the city.
We should acquire new users.
We should establish new patterns.
We should secure a retention rate.
Community and human-centered tools should be developed.
Visual and Interactive Communication
My research emphasizes visual communication to transparently communicate with communities.
A transit desert refers to a region where transit demand surpasses transit supply. The model demonstrtaes a multi-class supervised learning model.
