Lowrank approximations based on randomized unitary transformations have several desirable properties they have low communication costs, are amenable to parallel implementation, and exploit the existence of fast transform algorithms. These inequalities are used to investigate the behavior of the singular values of a matrix under random sampling, and to derive convergence rates for each individual eigenvalue of a sample covariance matrix. When the approximant is substituted for the original matrix in computations, its sparsity allows one to employ faster sparsityexploiting algorithms. This thesis investigates the tradeoff between the accuracy and cost of generating such approximations. This thesis contributes bounds on the approximation error of nonuniform randomized sparsification schemes, measured in the spectral norm and two nphard norms that are of interest in computational graph theory and subset selection applications Buy now Thesis On Linear Algebra

Lowrank approximations based on randomized unitary transformations have several desirable properties they have low communication costs, are amenable to parallel implementation, and exploit the existence of fast transform algorithms. Randomized matrix sparsification algorithms set randomly chosen entries of the input matrix to zero. The performance of several such sketching schemes is empirically evaluated using a suite of canonical matrices drawn from machine learning and data analysis applications, and a framework is developed for establishing theoretical error bounds Thesis On Linear Algebra Buy now
This thesis studies three classes of randomized numerical linear algebra algorithms, namely (i) randomized matrix sparsification algorithms, (ii) lowrank approximation algorithms that use randomized unitary transformations, and (iii) lowrank approximation algorithms for positivesemidefinite (psd) matrices. In addition to studying these algorithms, this thesis extends the matrix laplace transform framework to derive chernoff and bernstein inequalities that apply to all the eigenvalues of certain classes of random matrices. The last class of algorithms considered are spsd sketching algorithms.
