Hi! I'm Jiwon Chang, a computer science PhD student. I research data management systems & machine learning at the University of Rochester with professor Fatemeh Nargesian.
My research interest is two-fold. First, how can we acquire data from data repositores to improve model performance? Second, how can we optimize queries where some clauses are given by models? The two objectives are synergistic, since data acquisition queries are often queries that include ML models. There are also fundamental structural similarities where both are naturally modelled as combinatorial optimization problems.
My interests outside of computer science include bug friends and houseplants, science fiction, gaming, minimal and intentional living.
