Why the “L” in VLA Isn’t Redundant: Position‑Aware Rebinding Boosts Instruction Generalization 20‑40%

The paper analyzes why Vision‑Language‑Action models fail when instructions are paraphrased, designs a grounded semantic re‑binding (GSR) method that restructures language flow, and demonstrates 20‑40% gains in instruction generalization across several VLA architectures on the LIBERO‑Para benchmark.
