Nested Learning is a new machine learning paradigm designed to address the challenges of continual learning, where current models struggle with retaining old knowledge while acquiring new skills. Unlike traditional approaches that treat model architecture and optimization algorithms as separate entities, Nested Learning integrates them into a unified system of interconnected, multi-level learning problems. This approach allows for simultaneous optimization and deeper computational depth, helping to mitigate issues like catastrophic forgetting. The concept is validated through a self-modifying architecture named "Hope," which shows improved performance in language modeling and long-context memory management compared to existing models. This matters because it offers a potential pathway to more advanced and adaptable AI systems, akin to human neuroplasticity.
