Study Notes
Least Squares Approach
- The best-fitting line through a set of points is found using the least squares method.
Orthogonal Diagonalization
- Orthogonal matrices are used to diagonalize a symmetric matrix.
- Note: This process is not applicable to any square matrix.
Gram-Schmidt Process
- The purpose of the Gram-Schmidt process is to orthogonalize a set of vectors.
Linear Algebra
- The singular value decomposition (SVD) can be used to find the orthogonal basis of the image and kernel of a linear transformation.
- When changing basis, the transition matrix from one basis to another is not the inverse of the transition matrix from the other basis to the first.
