orthogonal projection n. The two-dimensional graphic representation of an object formed by the perpendicular intersections of lines drawn from points on the object to a plane of projection. Also calledorthographic projection. American Heritage® Dictionary of the English Language, Fifth Edition. Copyrig...
,k, and x an l-dimensional vector. The orthogonal projection of x on the subspace spanned by the columns of A (assumed to be linearly independent) is given by (Appendix A) (5.65) where in complex spaces the transpose operation is replaced by the Hermitian one. One can easily check ...
If a vector y coincides with its orthogonal projection onto a subspace W , then y is in W . Si un vector y coincide con su proyección ortogonal sobre un subespacio W, entonces y está en W. k. Literature It now follows from Theorem 4 of Chapter 8 that E; is the orthogonal ...
The basic concept is to project each pixel vector onto a subspace which is orthogonal to the undesired signatures. This operation is an optimal interference suppression process in the least squares sense. Once the interfering signatures have been nulled, projecting the residual onto the signature of...
We further define a function f as normalized if the scalar product 〈f∣f〉=1; this is the function-space equivalent of a unit vector. We will find that great convenience results if the basis functions for our function space are normalized and mutually orthogonal, corresponding to the descript...
The formula for the orthogonal projection Let V be a subspace of R n . To find the matrix of the orthogonal projection onto V , the way we first discussed, takes three steps: (1) Find a basis v 1 , v 2 , . . . , v m for V . (2) Turn the basis v i into an orthon...

In order to deal with the classification problem for high-dimensional and small-sized data,a kind of support vector machine based on random subspace and orthogonal locality preserving projection was proposed.The random subspace method was used to select a feature subset from the original feature spac...
