Optimal Sketching for Residual Error Estimation for Matrix and Vector Norms
Yi Li, Honghao Lin, David P. Woodruff
We study the problem of residual error estimation for matrix and vector norms using a linear sketch. Such estimates can be used, for example, to quickly assess how useful a more ex…

Tight Lower Bounds for Directed Cut Sparsification and Distributed Min-Cut
Yu Cheng, Max Li, Honghao Lin +3
In this paper, we consider two fundamental cut approximation problems on large graphs. We prove new lower bounds for both problems that are optimal up to logarithmic factors. The f…
