About this paper
Toshiaki Tsuji
Toshiaki Tsuji investigated Mamba as a motion encoder for robotic imitation learning, demonstrating its ability to generate stable, continuous robot motions. The model achieved high success rates in real-world tasks with limited data, outperforming Transformers in practical robotic operations due to its inherent output continuity.
Key insights
- Mamba's continuous State Space Model (SSM) structure provides an intrinsic inductive bias that generates stable and continuous robot trajectories, which is critical for reliable physical robot control.
- For practical robotic imitation learning, the stability and continuity of the model's output can be more important for task success than achieving the absolute lowest Root Mean Squared Error (RMSE) in offline trajectory prediction.
- Simplified Mamba configurations with low SSM dimensionality and carefully managed parameters (e.g., fixed A matrix diagonals) can learn effectively from limited data and operate efficiently in real-time robotic applications.
