In-Context Imitation Learning via Next-Token Prediction

by Max (Letian) Fu*, Huang Huang*, Gaurav Datta*, Lawrence Yunliang Chen, William Chung-Ho Panitch, Fangchen Liu, Hui Li, and Ken Goldberg at UC Berkeley and Autodesk (*equal contribution).

[Paper] | [Project Page] | [Checkpoints] | [Dataset]

This repo contains the official implementation for In-Context Imitation Learning via Next-Token Prediction. We investigate how to extend few-shot, in-context learning capability of next-token prediction models to real-robot imitation learning. Specifically, given a few teleop demonstrations of the task, we want the model to predict what to do in a new setting, without additional finetuning on these demonstrations.

Further information please contact Max Fu and Huang Huang, or post an issue on Github!
