Reproducibility Variable Result LLM Response
Research Type Theoretical We show how to solve a number of problems in numerical linear algebra, such as least squares regression, ℓp-regression for any p 1, low rank approximation, and kernel regression, in time T(A)poly(log(nd))... Our algorithms show that, perhaps surprisingly, most of these optimization problems do not require much more time than that of a polylogarithmic number of matrix-vector multiplications.
