New randomized transform improves accuracy in least squares regression

By PulseAugur Editorial · [1 sources] ·

Researchers have introduced a new randomized transform for accelerating least squares regression problems. This method, combining Hadamard flattening, random permutation, and Gaussian pooling, aims to provide coordinate-wise accuracy guarantees for the solution vector. The new approach addresses limitations in previous work by ensuring conditional independence in the sketched problem, achieving the desired accuracy with fewer rows than prior methods. AI

    Hadamard Flattening and Gaussian Pooling Sketch for Least Squares with Coordinate-wise Guarantee

    arXiv:2608.26552v1 Announce Type: cross Abstract: Randomized sketch-and-solve algorithms accelerate overconstrained $\ell_2$ regression by replacing the input with a smaller problem. Standard subspace embeddings guarantee that the cost of the regression is nearly preserved, but c…
