Find the singular value decomposition of A = [ (3 2 2), (2 3 2) ] and determine the angle of rotation induced by U and V . Also, write the rank 1 decomposition of A in terms of the columns of U and rows of V . Can we do dimensionality reduction in this case?

Find a singular value decomposition for the matrix A = [ 1 0 -1, -1 1...

Find a singular value decomposition for the matrix A = [ 1 0 -1, -1 1 0] (that means 1 0 -1 is the first row and -1 1 0 is the second) If you could provide a step-by-step tutorial on how to complete this I'd greatly appreciate it.

LU Decomposition (i). Prove that for n equal to 2 or 3 there is a non-singular square (n by n) matrix which has no LU decomposition with L unit lower triangular and U upper triangular. (In fact, this is true for any integer ≥ 2.) (ii). We will see that all non-singular square matrices do have an LUP decomposition (some time soon in class). Here P is a permutation matrix, also defined in Appendix D and used in Chapter 28....

Question. Programming question: Dimension Reduction In this question, you are asked to run Singular Value Decomposition (SVD) on Fashion-MNIST data set, interpret the output and train generative classifiers for multi- nomial classification of 10 classes. For the Fashion-MNIST data set, you can find more details in the original GitHub website or Kaggle website. In this assignment, you are allowed to use a library implementation of SVD. For python users, we recommend scikit-learn’s implementation TruncatedSVD. Tasks: ?Load the training and test...

Q: (LU decomposition) Find the LU decomposition of A = [-3 2 5 1; 12 -4 -20 -2; -6 0 15 1; -9 6 35 4]. You can use the compact method which works within a single matrix or you can build L and U separately. State L and U explicitly, and verify (in Matlab) that A = L*U. Hint: Matlab's built-in lu function isn't useful, since it pivots.

Find the two scalars (in C) λ1 and λ2 so that A − λI is singular. For A = [11 1 -1] Use the fact that A − λI is singular iff det(A − λI) = 0. For each λi find a basis for RS(A−λiI). Each basis will consist of a single vector, verify that the two vectors you found are orthogonal.
