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

    Zhao Song, Lichen Zhang

    cs.DS · cs.LG · stat.ML

    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 coordinate-wise accuracy of the solution is more delicate: we want the solution vector itself to be close to the optimal solution in $\ell_\infty$ norm. In particular, we want to find a vector $x'\in \mathbb{R}^d$...
