Researchers have developed a framework using SHapley Additive exPlanations (SHAP) to analyze and improve the generalizability of reinforcement learning (RL) algorithms in robotics. This approach quantifies the impact of different algorithm and hyperparameter configurations on generalization gaps, providing a theoretical foundation and practical guidance for selecting optimal settings. Separately, a new model called Affordance-R1 integrates reinforcement learning with Chain-of-Thought reasoning to enhance affordance grounding in multimodal large language models, demonstrating robust zero-shot generalization and emergent reasoning capabilities.
