An Information Bottleneck (IB) approach applied to Behavior Cloning (BC) for robot manipulation mitigates latent representation redundancy, improving policy generalization. This method consistently yields higher success rates across various simulation benchmarks and real-world tasks, particularly for multimodal and multi-task settings.
Key insights
- Latent representation redundancy is a significant and often unaddressed challenge in Behavior Cloning for robot manipulation, directly impacting model generalization and robustness.
- The Information Bottleneck principle provides a theoretically grounded framework to explicitly address this redundancy, yielding more compact and task-relevant representations.
- Applying IB at the intermediate, fused feature level of multimodal inputs is both theoretically justified and practically effective, allowing for unified redundancy reduction across diverse sensory data.
