Learning When to Stop: Selective Imitation Learning Under Arbitrary Dynamics Shift

James Wang, Jonathan Pei, Surbhi Goel

Selective imitation learning lets agents stop acting when dynamics shift makes expert demonstrations unreliable, using a small set of validator policies.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Our algorithm, SeqRejectron, constructs a stopping rule using a small set of validator policies whose size is independent of the horizon or policy class. For deterministic policies, this yields horizon-free Õ(log|Π|/ε²) sample complexity, assuming sparse costs.

C2weakest assumption

The assumption that unlabeled state trajectories from the same expert are available in the test environment, together with the sparse-cost assumption needed for the deterministic horizon-free bound; if either fails the stated guarantees do not apply.

C3one line summary

SeqRejectron builds a stopping rule from a small set of validator policies to achieve horizon-free sample-complexity guarantees for selective imitation learning under arbitrary train-test dynamics shifts.
