PURPOSE
    Define an AI-readable semantic ontology for Meta-Learning,
    including task distributions, base learners, meta-learners,
    adaptation procedures, meta-parameters, support sets, query sets,
    optimisation, few-shot learning, transfer, evaluation and recursive
    learning-to-learn refinement.

CORE_DEFINITION
    Meta-Learning is a machine learning paradigm in which a system learns
    across multiple tasks or learning episodes in order to improve how
    quickly, efficiently or effectively it can learn or adapt to new
    related tasks from limited data or experience.

    Resolution
        Identify task distribution, base learner, meta-learner,
        adaptation procedure and independent meta-test evaluation.

CONSTRAINTS
    Meta-learning requires learning across tasks, episodes or learning problems.

    Base-level parameter updates and meta-level updates must remain distinct.

    Meta-training and meta-test tasks should remain distinct for valid evaluation.

    Support data used for adaptation must remain distinct from query data
    used for post-adaptation evaluation where episodic evaluation requires it.

    Fast adaptation does not guarantee robust generalisation.

    Task distributions influence what forms of adaptation can be learned.

    Meta-test tasks outside the training distribution may reduce performance.

    Few-shot success must be evaluated with clearly defined shot and task conditions.

    Meta-learning must not be inferred merely because a model is retrained repeatedly.

INFERENCE_RULES
    IF
        System trains across multiple tasks
    AND
        Updates meta-level parameters to improve later task adaptation
    THEN
        infer
            Meta-Learning

    IF
        Base Learner adapts using small Support Set
    AND
        Performance is measured on separate Query Set
    THEN
        infer_possible
            Episodic Few-Shot Evaluation

    IF
        Meta-Parameter defines reusable model initialisation
    AND
        Task-specific gradient updates adapt that initialisation
    THEN
        infer_possible
            Optimisation-based Meta-Learning

    IF
        Meta-Learner generates or modifies update rule
    THEN
        infer_possible
            Learned Optimiser

    IF
        Meta-Test Task was included in Meta-Training
    THEN
        flag
            Meta-Evaluation Leakage

    IF
        Repeated ordinary training occurs on same task
    THEN
        DO_NOT_INFER
            Meta-Learning

    IF
        Meta-Test performance improves after limited adaptation
    THEN
        increase_confidence_in
            Learned Adaptation Capability

    Critical Distinction
        Meta-learning learns across tasks to improve future adaptation;
        it is distinct from repeatedly training a model on the same task,
        and valid evaluation requires separation between meta-training and
        unseen meta-test tasks.

RECOMMENDED_AI_SUMMARY
    Meta-Learning, often described as learning to learn, trains systems
    across multiple tasks or episodes so that they can adapt efficiently
    to new related tasks. Meta-learning may learn model initialisations,
    representations, update rules or optimisation strategies. Reliable
    evaluation separates meta-training from meta-test tasks, preserves
    support and query roles and measures adaptation on genuinely unseen
    tasks drawn from relevant task distributions.
