Theia
Theia is a vision foundation model for robot learning that distills multiple off-the-shelf vision foundation models trained on varied vision tasks. Theia’s rich visual representations encode diverse visual knowledge, enhancing downstream robot learning. It was introduced in the paper Theia: Distilling Diverse Vision Foundation Models for Robot Learning, which also includes experiments demonstrating that Theia outperforms its teacher models and prior robot learning models using less training data and smaller model sizes. Demo videos can be found on the project page.
Model Details
The theia-tiny-patch16-224-cddsv model, uses DeiT-Tiny as a backbone, and simulatenously distills CLIP, Depth Anything, DINOv2, Segment Anything and ViT. For more information on usage, please visit the Theia repository.
