When Does On-Policy Interaction Help? Representational Tradeoffs in Value-Based Imitation Learning

- What happened
- Researchers introduced OVI, an imitation learning algorithm that uses value function estimation and expert interaction to reduce representational demands on learner models.
- Why it matters
- Matters for robotics engineers and ML practitioners building systems that learn from expert demonstrations with limited model capacity.
- Watch out
- OVI requires access to a linear maximization oracle and assumes the learner can represent the expert's value function, which may not hold in all practical settings.
