Yilun Du

I am a third-year PhD student at MIT EECS, advised by Prof. Leslie Kaelbling, Prof. Tomas Lozano-Perez and Prof. Joshua B. Tenenbaum. Previously, I obtained my bachelor's degree from MIT, worked at OpenAI and FAIR, and got a gold medal at the International Biology Olympiad.

I am interested in constructing machine learning tools that enable the development of autonomous embodied agents. As the world is always changing, models must be adapt to out-of-distribution examples at test time and incrementally learn from new experiences. Towards these challenges, my recent research uses the tools of iterative energy-based optimization as a mean to adapt to out-of-distribution samples and a way to construct composable systems which can combinatorially generalize and incrementally learn. Second, models should be able to infer and discover structure across a different modalities such as vision, text, sound and touch, such as the underlying three-dimensional geometry of the world. I am interested in leveraging neural fields as a generic way to discover such rich structure in the world. Finally I'm interested in broader applications of these tools to other domains such as computational biology.

Research Highlights
  • Compositionality: constructing modular / composable models which enable combinatorical generalization, incremental learning, and controllability.
  • Perception and Scene Understanding: inferring structured representations of the world for downstream embodied tasks.
  • Generative Modeling: constructing models of the world's structure.
  • Interactive Learning: building intelligent agents which may interact in the surrounding world.
