Multiple View Performers for Shape Completion

no code implementations13 Sep 2022 David Watkins-Valls, Peter Allen, Krzysztof Choromanski, Jacob Varley, Nicholas Waytowich

We propose the Multiple View Performer (MVP) - a new architecture for 3D shape completion from a series of temporally sequential views.

Multiscale Sensor Fusion and Continuous Control with Neural CDEs

no code implementations16 Mar 2022 Sumeet Singh, Francis McCann Ramirez, Jacob Varley, Andy Zeng, Vikas Sindhwani

Though robot learning is often formulated in terms of discrete-time Markov decision processes (MDPs), physical robots require near-continuous multiscale feedback control.

MT-Opt: Continuous Multi-Task Robotic Reinforcement Learning at Scale

no code implementations16 Apr 2021 Dmitry Kalashnikov, Jacob Varley, Yevgen Chebotar, Benjamin Swanson, Rico Jonschkowski, Chelsea Finn, Sergey Levine, Karol Hausman

In this paper, we study how a large-scale collective robotic learning system can acquire a repertoire of behaviors simultaneously, sharing exploration, experience, and representations across tasks.

Visionary: Vision architecture discovery for robot learning

no code implementations26 Mar 2021 Iretiayo Akinola, Anelia Angelova, Yao Lu, Yevgen Chebotar, Dmitry Kalashnikov, Jacob Varley, Julian Ibarz, Michael S. Ryoo

We propose a vision-based architecture search algorithm for robot manipulation learning, which discovers interactions between low dimension action inputs and high dimensional visual inputs.

Disentangled Planning and Control in Vision Based Robotics via Reward Machines

no code implementations28 Dec 2020 Alberto Camacho, Jacob Varley, Deepali Jain, Atil Iscen, Dmitry Kalashnikov

In this work we augment a Deep Q-Learning agent with a Reward Machine (DQRM) to increase speed of learning vision-based policies for robot tasks, and overcome some of the limitations of DQN that prevent it from converging to good-quality policies.

Ode to an ODE

no code implementations NeurIPS 2020 Krzysztof M. Choromanski, Jared Quincy Davis, Valerii Likhosherstov, Xingyou Song, Jean-Jacques Slotine, Jacob Varley, Honglak Lee, Adrian Weller, Vikas Sindhwani

We present a new paradigm for Neural ODE algorithms, called ODEtoODE, where time-dependent parameters of the main flow evolve according to a matrix flow on the orthogonal group O(d).

Learning Precise 3D Manipulation from Multiple Uncalibrated Cameras

no code implementations21 Feb 2020 Iretiayo Akinola, Jacob Varley, Dmitry Kalashnikov

In this work, we present an effective multi-view approach to closed-loop end-to-end learning of precise manipulation tasks that are 3D in nature.

MAT: Multi-Fingered Adaptive Tactile Grasping via Deep Reinforcement Learning

no code implementations10 Sep 2019 Bohan Wu, Iretiayo Akinola, Jacob Varley, Peter Allen

When this methodology is used to realize grasps from coarse initial positions provided by a vision-only planner, the system is made dramatically more robust to calibration errors in the camera-robot transform.

Workspace Aware Online Grasp Planning

1 code implementation29 Jun 2018 Iretiayo Akinola, Jacob Varley, Boyuan Chen, Peter K. Allen

This framework greatly improves the performance of standard online grasp planning algorithms by incorporating a notion of reachability into the online grasp planning process.

Multi-Modal Geometric Learning for Grasping and Manipulation

1 code implementation20 Mar 2018 Jacob Varley, David Watkins-Valls, Peter Allen

At runtime, the network is provided a partial view of an object and tactile information is acquired to augment the captured depth information.

Shape Completion Enabled Robotic Grasping

no code implementations27 Sep 2016 Jacob Varley, Chad DeChant, Adam Richardson, Joaquín Ruales, Peter Allen

At runtime, a 2. 5D pointcloud captured from a single point of view is fed into the CNN, which fills in the occluded regions of the scene, allowing grasps to be planned and executed on the completed object.
