Dual-Mind World Models: A General Framework for Learning in Dynamic Wireless Networks

Lingyi Wang, Rashed Shelim, Walid Saad +1

Despite the popularity of reinforcement learning (RL) in wireless networks, existing approaches that rely on model-free RL (MFRL) and model-based RL (MBRL) are data inefficient and…
