고유벡터
The principal axis on which a matrix (linear transformation) acts on an eigenvector
- Compute the determinant of which returns a polynomial
- Find the roots of polynomial which returns eigenvalues
- For each eigenvalue, solve which returns eigenvectors
After finding eigenvectors for the points in the box, we assume that the two vectors with smaller eigenvalues are parallel to the plane.
The variance of the data projected onto the Eigenvector becomes maximized.
