Split the Differences, Pool the Rest: Provably Efficient Multi-Objective Imitation

Claire Vernade, Luca Viano, Volkan Cevher, Ziyad Sheebaelhamd

MA-BC partitions conflicting expert data and pools the rest to recover Pareto-optimal policies faster than separate learners in multi-objective imitation.

✓ Portable graph bundle live · download bundle · merged state

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

MA-BC converges to Pareto-optimal policies at a faster statistical rate than any learner that considers each expert dataset independently, and is minimax optimal.

C2weakest assumption

The provided demonstrations come from Pareto-optimal experts in a MOMDP, and that observable conflicts in state-action pairs can be reliably partitioned without additional structure on the transition dynamics or reward functions.

C3one line summary

MA-BC partitions divergent expert data while pooling non-conflicting pairs in MOMDPs, converging faster to Pareto-optimal policies than independent learners and matching a new minimax lower bound.
