Contrastive Learning for Enhancing Robust Scene Transfer in Vision-based Agile Flight

no code implementations18 Sep 2023 Jiaxu Xing, Leonard Bauersfeld, Yunlong Song, Chunwei Xing, Davide Scaramuzza

The utility of a robot greatly depends on its ability to perform a task in the real world, outside of a well-controlled lab environment.

Contrastive Learning Representation Learning

Learning Deep Sensorimotor Policies for Vision-based Autonomous Drone Racing

no code implementations26 Oct 2022 Jiawei Fu, Yunlong Song, Yan Wu, Fisher Yu, Davide Scaramuzza

The resulting policy directly infers control commands with feature representations learned from raw images, forgoing the need for globally-consistent state estimation, trajectory planning, and handcrafted control design.

Policy Search for Model Predictive Control with Application to Agile Drone Flight

no code implementations7 Dec 2021 Yunlong Song, Davide Scaramuzza

In this work, we provide an answer by using policy search for automatically choosing high-level decision variables for MPC, which leads to a novel policy-search-for-model-predictive-control framework.

Learning High-Level Policies for Model Predictive Control

1 code implementation20 Jul 2020 Yunlong Song, Davide Scaramuzza

In this work, we leverage probabilistic decision-making approaches and the generalization capability of artificial neural networks to the powerful online optimization by learning a deep high-level policy for the MPC (High-MPC).
