Trevor Ablett

PhD candidate at University of Toronto in the STARS Lab.
Researching the intersection of machine learning, robotics, and humans.

For a full list of my published work, see my Google Scholar page. I am investigating methods for improving imitation learning algorithms for robotic manipulators, by making them more sample efficient and/or more applicable to the challenges of real robotic tasks.
