WebMay 3, 2024 · We also see that RvS-R is competitive with the methods that use temporal difference (TD) learning, including CQL-R (Kumar et al., 2024), TD3+BC (Fujimoto et al., 2024), and Onestep (Brandfonbrener et al., 2024). However, the TD learning methods have an edge because they perform especially well on the random datasets.
