On Strategyproof Conference Peer Review

1 code implementation16 Jun 2018 Yichong Xu, Han Zhao, Xiaofei Shi, Jeremy Zhang, Nihar B. Shah

We then empirically show that the requisite property on the authorship graph is indeed satisfied in the submission data from the ICLR conference, and further demonstrate a simple trick to make the partitioning method more practically appealing for conference peer review.

Sublinear Time Numerical Linear Algebra for Structured Matrices

no code implementations12 Dec 2019 Xiaofei Shi, David P. Woodruff

For example, in the overconstrained $(1+\epsilon)$-approximate polynomial interpolation problem, $A$ is a Vandermonde matrix and $T(A) = O(n \log n)$; in this case our running time is $n \cdot \poly(\log n) + \poly(d/\epsilon)$ and we recover the results of \cite{avron2013sketching} as a special case.
