John Seon Keun Yi

I am a Computer Science Ph.D student at Boston University. I am fortunate to be advised by Prof. Dokyun "DK" Lee.

I received Masters and Bachelors degrees in Computer Science from Georgia Institute of Technology, where I worked on data-efficient learning and methodologies for human-robot interaction.

arXiv, 2021
paper

We use semantic scene graphs to disambiguate referring expressions in an interactive object grounding scenario. This is effectively useful in scenes with multiple identical objects.
