    Definition

    Position encoding makes the order of elements recognizable to models.

    Additional information with which a sequence model maps order or relative position of elements.

    Simply explained

    Words receive additional position cues so that their order is not lost.

    Why it matters in practice

    The term helps to select, develop, evaluate AI systems in a well-founded manner and realistically assess their technical risks.

    Example from business

    Possible example: A model supplements text blocks with position information so that it can distinguish their order in the input.

    Limits and pitfalls

    • Treating all variants as interchangeable or ignoring maximum training length.

    Origin & history

    The 2017 Transformer used sinusoidal and learned position encodings; many variants followed.

    Use in mid-sized companies

    • Possible application: Tokens receive position information so that word order remains distinguishable.
