New notions of simultaneous diagonalizability of quadratic forms with applications to QCQPs

no code implementations28 Jan 2021 Alex L. Wang, Rujun Jiang

Specifically, we say that a set of quadratic forms is almost SDC (ASDC) if it is the limit of SDC sets and d-restricted SDC (d-RSDC) if it is the restriction of an SDC set in up to d-many additional dimensions.

Weighted Cheeger and Buser Inequalities, with Applications to Clustering and Cutting Probability Densities

no code implementations20 Apr 2020 Timothy Chu, Gary L. Miller, Noel J. Walkington, Alex L. Wang

In this paper, we show how sparse or isoperimetric cuts of a probability density function relate to Cheeger cuts of its principal eigenfunction, for appropriate definitions of `sparse cut' and `principal eigenfunction'.
