Two new research papers explore advanced training methods for Generative Flow Networks (GFlowNets). The first paper introduces a policy-gradient-based framework that bridges GFlowNet's flow balance with reinforcement learning's accumulated reward, offering new policy-based training approaches and a coupled strategy for forward and backward policy optimization. The second paper frames GFlowNet forward-policy training through information geometry, utilizing the Fisher-Rao metric and natural gradients to derive efficient, structure-aware training methods that can be empirically illustrated.
