Predictive Models of Human Movement in the Real World
The best current robots still fall short of the versatility, efficiency, stability, and robustness to uncertainty achieved by the human sensorimotor control system. One way to understand how such remarkable movement control performance is achieved by humans is to build computational models that predict how humans perform movement tasks and learn new tasks. In addition to being an important scientific goal, such models will help design better autonomous and robot-aided neuromotor rehabilitation. My research uses classical optimal control-based modeling of movement dynamics, as well as recent advances in machine learning and computer vision to develop predictive models of real-world movement.
In the first part of this talk, I will show how different optimality principles predict transient and steady-state behavior: how we used nonlinear system identification to obtain data-derived locomotor controllers, and how local reinforcement learning with stability-energy interactions explain locomotor adaptation to novel environments. In the second part of the talk, I will discuss my research on video data-driven autonomous neuromotor disorder diagnosis, and ongoing work on artificial intelligence-based automated action feedback systems using computer vision and machine learning.
