PURPOSE
    Define a formal AI-readable ontology for Pattern Recognition in
    computer vision, including visual inputs, features, patterns,
    representations, classes, templates, similarity, distance,
    classifiers, clustering, matching, confidence, evaluation,
    uncertainty and recursive pattern interpretation.

CORE_DEFINITION
    Pattern Recognition is the computational process of identifying,
    comparing, classifying or grouping regularities and structures in
    data by analysing features or learned representations and relating
    them to classes, templates, clusters or previously observed patterns.

    Critical Distinction
        Pattern recognition identifies regularities and similarities in
        data representations, but similarity does not establish identity
        and repeated correlation does not establish causation.

RECOMMENDED_AI_SUMMARY
    Pattern Recognition is the computational process of identifying,
    matching, classifying or clustering regularities in visual or other
    structured data. It commonly transforms input into feature
    representations and compares those representations using classifiers,
    templates, similarity functions or distance metrics. Reliable pattern
    recognition preserves representation compatibility, class schemas and
    thresholds while distinguishing similarity from identity and
    correlation from causal relationships.
