Towards Batch-to-Streaming Deep Reinforcement Learning for Continuous Control

The paper introduces two new streaming deep reinforcement learning algorithms—Streaming Soft Actor-Critic (S2AC) and Streaming Deterministic Actor-Critic (SDAC)—designed to work with state‑of‑the‑art batch RL methods and suitable for on‑device fine‑tuning, such as Sim2Real transfer. These algorithms achieve performance comparable to existing streaming baselines on standard benchmarks without the need for extensive per‑environment hyperparameter tuning. The authors also examine the challenges of transitioning from batch to streaming RL, demonstrating that a naive approach can degrade pre‑trained policy performance and propose a principled solution to mitigate this issue.
