Lecture 15 : Additive - error Low - rank Matrix Approximation with Sampling and Projections

نویسنده

  • Michael Mahoney
چکیده

• A spectral norm bound for reconstruction error for the basic low-rank approximation random sampling algorithm. • A discussion of how similar bounds can be obtained with a variety of random projection algorithms. • A discussion of possible ways to improve the basic additive error bounds. • An iterative algorithm that leads to additive error with much smaller additive scale. This will involve using the additive error sampling algorithm in an iterative manner in order to drive down the additive error quickly as a function of the number of iterations.

Lecture 16: Relative-error Low-rank Matrix Approximation with Sampling and Projections

Today, we will start to discuss how to improve the rather coarse additive-error low-rank matrix approximation algorithms from the last two classes to obtain much better results for low-rank matrix approximation. Importantly, “better” means very different things to different research communities, and thus we will discuss several different notions of better. We will start by describing how to imp...

Lecture 14: Additive-error Low-rank Matrix Approximation with Sampling and Projections

Today, we will shift gears and begin to discuss RandNLA algorithms for low-rank matrix approximation. We will start with additive-error low-rank matrix approximation with sampling and projections. These are of interest historically and since they illustrate several techniques (normsquared sampling, simple linear algebraic manipulations, the use of matrix perturbation theory, etc.), but they are...

Adaptive Sampling and Fast Low-Rank Matrix Approximation

We prove that any real matrix A contains a subset of at most 4k/ + 2k log(k + 1) rows whose span “contains” a matrix of rank at most k with error only (1 + ) times the error of the best rank-k approximation of A. We complement it with an almost matching lower bound by constructing matrices where the span of any k/2 rows does not “contain” a relative (1 + )-approximation of rank k. Our existence...

Matrix Approximation and Projective Clustering via Iterative Sampling

We present two new results for the problem of approximating a given real m × n matrix A by a rank-k matrix D, where k < min{m, n}, so as to minimize ||A−D||F . It is known that by sampling O(k/ε) rows of the matrix, one can find a low-rank approximation with additive error ε||A||F . Our first result shows that with adaptive sampling in t rounds and O(k/ε) samples in each round, the additive err...
