Parameter-Free Triangle Counting
Asaf Etgar, Anna Gilbert, Quanquan Liu +1
Given an undirected, unweighted graph with vertices and edges, the triangle counting problem seeks the number of three-cycles in it. Triangle and subgraph count…
Scalable Triangle Counting: The Threshold Algorithm
Asaf Etgar, Anna Gilbert, Quanquan C. Liu +1
We study one-pass triangle counting on random-order edge streams. We present a remarkably simple algorithm---read edges from the stream until triangles are observed in the pref…
Metric repair is two problems: Which edges, and what weights
Asaf Etgar, Anna Gilbert
Real distance data rarely cooperate: measurements are noisy, observations are missing, and the numbers that result seldom satisfy the triangle inequality. A family of methods exist…
Structural Tractability Frontiers for Metric Repair
Asaf Etgar, Anna C. Gilbert, Jamie Tucker-Foltz
Given a graph labeled with positive distances on each edge, what is the fewest number of edge distances that must be modified for to become a metric? It is known that this…
How can classical multidimensional scaling go wrong?
Rishi Sonthalia, Gregory Van Buskirk, Benjamin Raichel +1
Given a matrix describing the pairwise dissimilarities of a data set, a common task is to embed the data points into Euclidean space. The classical multidimensional scaling (cM…
Dual Regularized Optimal Transport
Rishi Sonthalia, Anna C. Gilbert
In this paper, we present a new formulation of unbalanced optimal transport called Dual Regularized Optimal Transport (DROT). We argue that regularizing the dual formulation of opt…
