Researchers have developed a new method to evaluate offline goal-conditioned reinforcement learning (GCRL) beyond just success rates. The study introduces "trainability landscapes" to visualize how different optimization parameters affect a method's ability to learn and extract goal-conditioned signals into policies. This approach reveals that high-scoring methods can be either broadly accessible or brittle, and that peak performance alone does not guarantee extractable behavior. The findings suggest that analyzing these landscapes and using extraction diagnostics can provide a more nuanced understanding of GCRL method performance. AI
