From Pixels to Torques with Linear Feedback
Jeong Hun Lee, Sam Schoedel, Aditya Bhardwaj +1
We demonstrate the effectiveness of simple observer-based linear feedback policies for "pixels-to-torques" control of robotic systems using only a robot-facing camera. Specifically…

Data-Efficient Model Learning for Control with Jacobian-Regularized Dynamic-Mode Decomposition}
Brian E. Jackson, Jeong Hun Lee, Kevin Tracy +1
We present a data-efficient algorithm for learning models for model-predictive control (MPC). Our approach, Jacobian-Regularized Dynamic-Mode Decomposition (JDMD), offers improved…
