projisoinnit
Projisoinnit is a Finnish term referring to the act or result of projecting a object, data, or vector from a higher-dimensional space onto a subspace or lower-dimensional space. They appear in several fields, including mathematics, computer graphics, statistics, and signal processing, where a projection identifies a component aligned with a chosen subspace.
In mathematics, a projection is a linear operator P satisfying P^2 = P. If the projection is also
In computer graphics, projisoinnit include perspective projections that map three-dimensional points to a two-dimensional image plane.
In statistics and signal processing, projections are used for dimensionality reduction and least-squares fitting. Data can
