First author; full author list to be finalized.

Given an existing policy, ABI trains only a reusable guide. The guide improves task execution at deployment while the policy stays frozen, with no parameter updates or task-specific policy post-training.

Demo

Same policy, with and without ABI

Manipulation, locomotion and navigation excerpts from the project video. Each pair uses the same starting state, random seed and frozen base policy. Selected simulation examples with edited playback speeds; on-screen scores describe these development episodes.

A preview of ongoing work. The paper and method details will follow with the release.
