New SQAM method enhances reinforcement learning for flow policies

By PulseAugur Editorial · [2 sources] ·

Researchers have developed a new method called Q-learning with Scalar Adjoint Matching (SQAM) to improve the fine-tuning of flow policies in reinforcement learning. This technique addresses the computational cost of traditional adjoint matching by deriving a closed-form scalar adjoint that eliminates per-step vector-Jacobian products. SQAM has shown significant success in challenging OGBench domains, outperforming existing baselines by 18 to 35 percentage points, and has also demonstrated effectiveness in fine-tuning large vision-language-action policies on real-world robotic tasks.

    Q-Learning with Scalar Adjoint Matching

    Flow policies capture rich and diverse action distributions, and fine-tuning them with off-policy RL to improve beyond the demonstrations has drawn growing interest. However, fine-tuning a flow policy against a learned value function is not trivial, because the policy generates i…
