🔘Body Transformer: Leveraging Robot Embodiment for Policy Learning

what: one transformer to control whole body.
- propose Body Transformer (BoT)
- vanilla transformer with special attention mask, which reflects interconnection of the different body parts.

🔘CrossFormer Scaling Cross-Embodied Learning for Manipulation, Navigation, Locomotion, and Aviation

what: One transformer that can control various robot types.
- trained on 900K trajectories from 20 different robots.
- matches or beats specialized algorithms for each robot type.
- works on arms, wheeled bots, quadrupeds, and even drones.

Diffusion + AR Transformers

🟢Transfusion: Predict the Next Token and Diffuse Images with One Multi-Modal Model

what: merge AR decoder with vanilla diffusion.
- train model with two objectives: causal language loss + diffusion objective
- deal with discrete and continuous in the same model.

🟡 Discrete Diffusion Modeling by Estimating the Ratios of the Data Distribution

what: propose diffusion for discrete distribution
- beats other diffusion approach for text generation
- outperforms gpt-2.

🟡Show-o: One Single Transformer to Unify Multimodal Understanding and Generation

what: combine AR transformer with MaskGIT.
- can generate image and understand them.
- text tokenization + image tokenization. Use MaskGIT losses for image tokens.
