Leveraging Predictive Models for Adaptive Sampling of Spatiotemporal Fluid Processes

no code implementations3 Apr 2023 Sandeep Manjanna, Tom Z. Jiahao, M. Ani Hsieh

Our algorithm makes use of the predictions from a learned prediction model to plan a path for an autonomous vehicle to adaptively and efficiently survey the region of interest.

Online Dynamics Learning for Predictive Control with an Application to Aerial Robots

1 code implementation19 Jul 2022 Tom Z. Jiahao, Kong Yao Chee, M. Ani Hsieh

To improve the adaptiveness of the model and the controller, we propose an online dynamics learning framework that continually improves the accuracy of the dynamic model during deployment.

KNODE-MPC: A Knowledge-based Data-driven Predictive Control Framework for Aerial Robots

no code implementations10 Sep 2021 Kong Yao Chee, Tom Z. Jiahao, M. Ani Hsieh

Using a quadrotor, we benchmark our hybrid model against a state-of-the-art Gaussian Process (GP) model and show that the hybrid model provides more accurate predictions of the quadrotor dynamics and is able to generalize beyond the training data.
