A flat surface that is one dimension smaller than the space it sits in
  • noun
  • /ˈhaɪpərˌpleɪn/
  • Specialized
: hiperplano
  • In three-dimensional space, a hyperplane is a flat surface that divides the space into two half-spaces.

Examples

  • The objective is to find the best hyperplane that stratifies the two classes with the largest margin.

  • So you have these linear constraints that turns out to define hyperplanes in N dimensions.

  • This would be a hyperplane in in three space.

  • Now restrict to this hyperplane and ask yourself the same question.

  • The optimal solution was taken to be that in which the number of variables in the 0.1 hyperplane was maximized.

    Academic text (1990)
  • It involves the fitting of a few hyperplanes to scatter points.

    Academic text (1992)
  • This margin defines the maximal width of the two slabs parallel to the hyperplane that have no interior data points.

    Academic text (2016)
  • The algorithm's goal is to determine the optimal hyperplane that separates the data points into distinct classes.

  • To visualize complex data, we often project it onto a lower dimension by using a hyperplane.

Morphology

hyperplane = plane (semi-transparent) = hyper + plane

The word clearly combines 'hyper-' with 'plane', but its exact mathematical meaning is a specialized extension rather than a fully predictable everyday interpretation.

Etymology

The word hyperplane joins the first part hyper- meaning 'over' or 'beyond' and plane meaning a flat surface, like the familiar word 'plane' for a flat area. So, a hyperplane is like a flat sheet that sits in a space with more dimensions and is one dimension smaller than the space around it.
