Learning to Plan with Personalized Preferences

Effective integration of AI agents into daily life requires them to understand and adapt to individual human preferences, particularly in collaborative roles. We develop agents that not only learn preferences from few demonstrations but also learn to adapt their planning strategies based on these preferences.

Install

You should firstly install NVIDIA Omniverse and Omnigibson based on the following tutorials:

NVIDIA Omniverse: https://docs.omniverse.nvidia.com/install-guide/latest/index.html  
Omnigibson: https://behavior.stanford.edu/omnigibson/getting_started/installation.html

Our code is developed on the version 2023.1.1 of Isaac Sim. We recommend using a machine with RAM 32GB+ and NVIDIA RTX 2070+ following OmniGibson's requirements. The code can be run on a headless machine via docker, but we recommend using a machine with a display.

After successfully install Omnigibson, test on some demos:

# simple navigation
python benchmark/examples/nav_demo.py
# pick and place
python benchmark/examples/pick_and_place.py

Benchmark

We define human preference in three different levels. We provide code to help sample demos of these preference in different scenes. You can also modify the sampling code to generate more customed demos.

cd level_x && python sample.py

where sample.py mainly consists the sampling loop, preference.py mainly consists the main preference logic, and task.py hosts the task environment.

We also provide a subset of our sampled dataset at huggingface. (Note: This dataset is unfiltered and may include some crash demos caused by instability during rendering in Omnigibson. We recommend performing the rendering process independently for optimal results.)

A demonstration includes an egocentric video of agent activity, a bird's-eye-view map tracking agent position, and frame-level action annotations. We also provide third-person view recordings for enhanced visualization.

We prioritize the egocentric perspective for two reasons: 1) it offers a clear view with minimal occlusions, and 2) it aligns with human perception, facilitating transfer to real-world data from head-mounted devices.

Baselines

We provide all our implementations of the baselines in the baseline folder. For each baseline, we recommend creating an independent conda environment to avoid conflict. Navigate to each folder to see the install steps.
