arXiv:2602.14761v2 Announce Type: replace-cross Abstract: Current meta-learning methods are constrained to narrow task distributions with fixed feature and label spaces, limiting applicability. Moreover, the current meta-learning literature uses key terms like "universal" and "general-purpose" inconsistently and lacks precise definitions, hindering comparability. We introduce a theoretical framework for meta-learning which formally defines practical universality and introduces a distinction between algorithm-explicit and algorithm-implicit learning, providing a principled vocabulary for reason
The paper addresses current limitations and definitional inconsistencies in meta-learning research, which is a rapidly advancing subfield of AI seeking more general capabilities.
This theoretical framework could provide a more robust and universal approach to meta-learning, forming a foundational piece for future developments in general AI.
The explicit definition of 'universal' and the distinction between algorithm-explicit and algorithm-implicit learning could unify and accelerate research efforts in meta-learning, leading to more broadly applicable AI systems.

The new framework allows for the creation of more adaptive and less constrained meta-learning algorithms.
This could lead to significantly more versatile AI agents capable of learning across diverse, undefined task environments.
Advances in general-purpose learning could fundamentally alter the economics of AI development, shifting value toward fundamental architectural innovation.
