This paper introduces Deep Predictive Learning (DPL), a concept for robot motion learning inspired by predictive coding theory and the free-energy principle, which enables robots to learn and adapt by continuously minimizing prediction errors between their internal models and real-world sensory inputs. DPL demonstrates the ability to learn complex, scalable, and versatile manipulation tasks, including deformable object handling and language-conditioned behaviors, with data efficiency in real-world environments.

Key insights

• Robot intelligence can emerge from the continuous prediction of sensorimotor states and online minimization of prediction errors, inspired by predictive coding theory and the free-energy principle.
• The Deep Predictive Learning (DPL) framework enables robust, adaptive robot behavior by continuously correcting internal models and actively interacting with the environment to reduce prediction discrepancies.
• Hierarchical model structures with varying timescales and integrated attention mechanisms allow for both immediate error absorption and long-term behavioral adaptation, leading to robust and flexible task execution.
