GFlowNet training methods explored via policy gradients and information geometry · 2 sources tracked

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.

    Information-Geometric Forward Policy Training in GFlowNets

    arXiv:2608.03967v1 Announce Type: new Abstract: Generative Flow Networks (GFlowNets) have emerged as a flexible framework for amortised inference over discrete and mixed discrete-continuous objects, requiring only an unnormalised target density specified through a reward. In this…
