no code implementations15 Apr 2024 Amir Bar, Arya Bakhtiar, Danny Tran, Antonio Loquercio, Jathushan Rajasegaran, Yann Lecun, Amir Globerson, Trevor Darrell

Animals perceive the world to plan their actions and interact with other agents to accomplish complex tasks, demonstrating capabilities that are still unmatched by AI systems.

Conformal Policy Learning for Sensorimotor Control Under Distribution Shifts

no code implementations2 Nov 2023 Huang Huang, Satvik Sharma, Antonio Loquercio, Anastasios Angelopoulos, Ken Goldberg, Jitendra Malik

The key idea is the design of switching policies that can take conformal quantiles as input, which we define as conformal policy learning, that allows robots to detect distribution shifts with formal statistical guarantees.

Learning Vision-based Pursuit-Evasion Robot Policies

no code implementations30 Aug 2023 Andrea Bajcsy, Antonio Loquercio, Ashish Kumar, Jitendra Malik

We find that the quality of the supervision signal for the partially-observable pursuer policy depends on two key factors: the balance of diversity and optimality of the evader's behavior and the strength of the modeling assumptions in the fully-observable policy.

Learning Visual Locomotion with Cross-Modal Supervision

no code implementations7 Nov 2022 Antonio Loquercio, Ashish Kumar, Jitendra Malik

In this work, we show how to learn a visual walking policy that only uses a monocular RGB camera and proprioception.

Training Efficient Controllers via Analytic Policy Gradient

1 code implementation26 Sep 2022 Nina Wiedemann, Valentin Wüest, Antonio Loquercio, Matthias Müller, Dario Floreano, Davide Scaramuzza

Conversely, learning-based offline optimization approaches, such as Reinforcement Learning (RL), allow fast and efficient execution on the robot but hardly match the accuracy of MPC in trajectory tracking tasks.

Learning a Single Near-hover Position Controller for Vastly Different Quadcopters

no code implementations19 Sep 2022 Dingqi Zhang, Antonio Loquercio, Xiangyu Wu, Ashish Kumar, Jitendra Malik, Mark W. Mueller

This paper proposes an adaptive near-hover position controller for quadcopters, which can be deployed to quadcopters of very different mass, size and motor constants, and also shows rapid adaptation to unknown disturbances during runtime.

Visual Attention Prediction Improves Performance of Autonomous Drone Racing Agents

no code implementations7 Jan 2022 Christian Pfeiffer, Simon Wengeler, Antonio Loquercio, Davide Scaramuzza

This work investigates whether neural networks capable of imitating human eye gaze behavior and attention can improve neural network performance for the challenging task of vision-based autonomous drone racing.

Learning High-Speed Flight in the Wild

1 code implementation11 Oct 2021 Antonio Loquercio, Elia Kaufmann, René Ranftl, Matthias Müller, Vladlen Koltun, Davide Scaramuzza

Indeed, the subtasks are executed sequentially, leading to increased processing latency and a compounding of errors through the pipeline.

Jointly Learning Identification and Control for Few-Shot Policy Adaptation

no code implementations29 Sep 2021 Nina Wiedemann, Antonio Loquercio, Matthias Müller, Rene Ranftl, Davide Scaramuzza

We evaluate our approach on several complex systems and tasks, and experimentally analyze the advantages over model-free and model-based methods in terms of performance and sample efficiency.

AutoTune: Controller Tuning for High-Speed Flight

1 code implementation19 Mar 2021 Antonio Loquercio, Alessandro Saviolo, Davide Scaramuzza

To answer the first question, we study the relationship between parameters and performance and find out that the faster the maneuver, the more sensitive a controller becomes to its parameters.

Primal-Dual Mesh Convolutional Neural Networks

1 code implementation NeurIPS 2020 Francesco Milano, Antonio Loquercio, Antoni Rosinol, Davide Scaramuzza, Luca Carlone

Recent works in geometric deep learning have introduced neural networks that allow performing inference tasks on three-dimensional geometric data by defining convolution, and sometimes pooling, operations on triangle meshes.

Flightmare: A Flexible Quadrotor Simulator

3 code implementations1 Sep 2020 Yunlong Song, Selim Naji, Elia Kaufmann, Antonio Loquercio, Davide Scaramuzza

State-of-the-art quadrotor simulators have a rigid and highly-specialized structure: either are they really fast, physically accurate, or photo-realistic.

Event-based Asynchronous Sparse Convolutional Networks

1 code implementation ECCV 2020 Nico Messikommer, Daniel Gehrig, Antonio Loquercio, Davide Scaramuzza

However, these approaches discard the spatial and temporal sparsity inherent in event data at the cost of higher computational complexity and latency.

Learning Depth With Very Sparse Supervision

no code implementations2 Mar 2020 Antonio Loquercio, Alexey Dosovitskiy, Davide Scaramuzza

Motivated by the astonishing capabilities of natural intelligent agents and inspired by theories from psychology, this paper explores the idea that perception gets coupled to 3D properties of the world via interaction with the environment.

Global-Local Network for Learning Depth with Very Sparse Supervision

no code implementations25 Sep 2019 Antonio Loquercio, Alexey Dosovitskiy, Davide Scaramuzza

Natural intelligent agents learn to perceive the three dimensional structure of the world without training on large datasets and are unlikely to have the precise equations of projective geometry hard-wired in the brain.

A General Framework for Uncertainty Estimation in Deep Learning

1 code implementation16 Jul 2019 Antonio Loquercio, Mattia Segù, Davide Scaramuzza

Current approaches for uncertainty estimation of neural networks require changes to the network and optimization process, typically ignore prior knowledge about the data, and tend to make over-simplifying assumptions which underestimate uncertainty.
