Researchers have introduced "trajectory balance," a novel learning objective for Generative Flow Networks (GFlowNets). This new objective aims to improve credit assignment in GFlowNets, which are used for generating compositional objects like graphs and strings from unnormalized densities. The proposed method is presented as a more efficient alternative to existing objectives such as flow matching and detailed balance, which can struggle with long action sequences. Experiments across four domains demonstrated trajectory balance's effectiveness in enhancing GFlowNet convergence, sample diversity, and robustness. AI
