I am Linfeng Zhao (赵林风), a CS Ph.D. student at Khoury College of Computer Sciences of Northeastern University since 2019. I’m advised by Prof. Lawson L.S. Wong and also working with Robin Walters. My research interests lie in the intersection of machine learning, robotics and artificial intelligence.
I study how structure helps improve learning and generalization in robotics and model-based reinforcement learning, such as: (1) structured representation learning of state and action, (2) factored/structured world modeling and planning, etc.
We formulate how differentiable planning algorithms can exploit inherent symmetry in path planning problems, named SymPlan, and propose practical algorithms.
We formulate compositional generalization in object-oriented world modeling, and propose a soft and efficient mechanism for practice.
