PLEX: Making the Most of the Available Data for Robotic Manipulation Pretraining

no code implementations15 Mar 2023 Garrett Thomas, Ching-An Cheng, Ricky Loynd, Felipe Vieira Frujeri, Vibhav Vineet, Mihai Jalobeanu, Andrey Kolobov

A rich representation is key to general robotic manipulation, but existing approaches to representation learning require large amounts of multimodal demonstrations.

Relational Attention: Generalizing Transformers for Graph-Structured Tasks

1 code implementation11 Oct 2022 Cameron Diao, Ricky Loynd

Transformers flexibly operate over sets of real-valued vectors representing task-specific entities and their attributes, where each vector might encode one word-piece token and its position in a sequence, or some piece of information that carries no position at all.

MoCapAct: A Multi-Task Dataset for Simulated Humanoid Control

1 code implementation15 Aug 2022 Nolan Wagener, Andrey Kolobov, Felipe Vieira Frujeri, Ricky Loynd, Ching-An Cheng, Matthew Hausknecht

We demonstrate the utility of MoCapAct by using it to train a single hierarchical policy capable of tracking the entire MoCap dataset within dm_control and show the learned low-level component can be re-used to efficiently learn downstream high-level tasks.

Now I Remember! Episodic Memory For Reinforcement Learning

no code implementations ICLR 2018 Ricky Loynd, Matthew Hausknecht, Lihong Li, Li Deng

Humans rely on episodic memory constantly, in remembering the name of someone they met 10 minutes ago, the plot of a movie as it unfolds, or where they parked the car.
