The authors propose a language-critique framework for imitation learning from suboptimal demonstrations that uses natural language as a structured supervision signal instead of scalar signals.

- The method constructs language labels from demonstrations that describe current progress, identify suboptimal behaviors, and provide fine-grained corrective guidance.
- The authors introduce a language-critique loss that trains policies using these structured signals without reducing them to scalars.
- The loss is instantiated for both behavior cloning and diffusion policies, yielding two methods named LC-BC and LC-DP.
