Latent Particle World Models (LPWM)

Project Website | Paper | GitHub

Latent Particle World Model (LPWM) is a self-supervised object-centric world model scaled to real-world multi-object datasets and applicable in decision-making. LPWM autonomously discovers keypoints, bounding boxes, and object masks directly from video data, enabling it to learn rich scene decompositions without supervision. The architecture is trained end-to-end purely from videos and supports flexible conditioning on actions, language, and image goals.

Sample Usage

To train LPWM on a dataset like Sketchy using the official implementation, you can use the following commands:

# Install environment
conda env create -f environment.yml
conda activate dlp

# Train LPWM on Sketchy
python train_lpwm.py --dataset sketchy
