me and my sister 🐠

Hi! I am Yujin Bae, a second-year M.S. student at KAIST, where I am advised by Prof. Kuk-Jin Yoon in the Visual Intelligence Lab.

My long-term goal is to build proactive assistive AI for embodied settings such as smart glasses and robotic hands. Toward this end, I focus on multimodal understanding of how humans interact with their surroundings, and I aim to extend this understanding to robot learning as a next step.

Concretely, my interests span:

  • Anticipation — forecasting human motion and action semantics from egocentric video and sparse wearable sensors
  • Understanding — efficient egocentric video understanding with multimodal LLMs, guided by human behavior
  • Transfer — learning dexterous manipulation policies from human video

Before joining KAIST, I received my B.S. at Ewha Womans University (ranked 1st in major!), and spent a semester as an exchange student at the University of Vermont.
