SPALS: Fast Alternating Least Squares via Implicit Leverage Scores Sampling

no code implementations NeurIPS 2016 Dehua Cheng, Richard Peng, Yan Liu, Ioakeim Perros

In this paper, we show ways of sampling intermediate steps of alternating minimization algorithms for computing low rank tensor CP decompositions, leading to the sparse alternating least squares (SPALS) method.

On Bochner's and Polya's Characterizations of Positive-Definite Kernels and the Respective Random Feature Maps

no code implementations27 Oct 2016 Jie Chen, Dehua Cheng, Yan Liu

A well-known construction of such functions comes from Bochner's characterization, which connects a positive-definite function with a probability distribution.

Spectral Sparsification of Random-Walk Matrix Polynomials

no code implementations12 Feb 2015 Dehua Cheng, Yu Cheng, Yan Liu, Richard Peng, Shang-Hua Teng

Our work is particularly motivated by the algorithmic problems for speeding up the classic Newton's method in applications such as computing the inverse square-root of the precision matrix of a Gaussian random field, as well as computing the $q$th-root transition (for $q\geq1$) in a time-reversible Markov model.
