Data Efficient RLVR via Off-Policy Influence Guidance (2026.acl-long)

Copied to clipboard

Challenge: Existing data selection methods for RLVR are heuristic-based, lacking theoretical guarantees and generalizability.
Approach: They propose an off-policy influence estimation method that approximates data influence using offline trajectories.
Outcome: The proposed method reduces the computational cost of policy rollouts and improves storage and computation efficiency.
