Proximal Policy Optimization Enhances GFlowNet Training for Discrete Sampling

Researchers have developed a new application of proximal policy optimization (PPO) within the Generative Flow Network (GFlowNet) framework. This method aims to improve the training of stochastic policies for sampling from complex discrete probability distributions. The paper demonstrates that PPO offers faster convergence and greater data efficiency compared to existing GFlowNet training objectives, with successful applications in areas like molecular graph generation.
