Finding "the red mug on the top shelf" in a 3D scan isn’t just about matching pixels—it’s about reasoning. Key takeaways * 3D visual grounding = teaching AI to locate an object in a 3D scene from a natural-language description. * Most systems rely on huge, hand-labeled 3D

Teach Robots to Learn Like People Building versatile embodied AI (agents that see, read, and act) is hard because real-world data is scarce and training is expensive. We introduce Deliberate Practice Policy Optimization (DPPO), a metacognitive "metaloop" that alternates between: * Supervised fine-tuning to expand general competence * Reinforcement learning
