How Repositioning the Language Path Boosts VLA Instruction Generalization by 20‑40%

The paper analyzes why Vision‑Language‑Action models fail when task instructions are paraphrased, demonstrates that language semantics remain partially encoded, and shows that the Grounded Semantic Re‑Binding (GSR) redesign of the language‑to‑action information flow improves instruction generalization by up to 40% across multiple VLA architectures.

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.
