Improving Generative Policies from Observational Data
In brief
- PolicyLift improves decision policies from observational data for structured actions.
- The method uses three stages to bypass off-policy evaluation limits and reduce costs.
- Experiments show systematic improvements over baseline policies.
A new method, PolicyLift, enhances decision-making policies from observational data for complex structured actions like text or images. It uses three steps to overcome off-policy evaluation limits and generation costs. Results show consistent improvements over existing policies.
