Linrätad

Linrätad is a term used in speculative and fictional contexts to describe a data-transformation technique that aims to map multi-dimensional sequences into a single linear order while preserving certain relational properties of the original data. In its most common fictional usage, linrätad is applied to datasets consisting of time stamps, categorical attributes, and continuous measurements, producing a linear representation suitable for sequential processing or visualization.

The name combines elements reminiscent of Scandinavian languages, drawing on lin for "line" and rätad as a form related to "to straighten" or "rectified." In the literature, the term is often introduced with a short etymology to underline its intended meaning in worldbuilding and thought experiments about information representation.

Several variants are described in fiction. A simple approach, sometimes called monotone linearization, orders data by a chosen key and then adjusts intermediate positions to reduce obvious cross-overs. A structure-preserving variant seeks to maintain approximate pairwise distances along the line, at the cost of occasional distortions. A deconvolution form attempts to factor multiple attributes into a single sequence using weighted scoring.

Linrätad is typically discussed as a visualization or conceptual tool. Its main advantages are computational simplicity and the ability to compare sequences at a glance. Its drawbacks include distortion of multidimensional relationships and sensitivity to the chosen ordering criteria. As a fictional construct, it serves as a thought experiment rather than a standardized method.
