An Improved Upper Bound for the Euclidean TSP Constant Using Band Crossovers
Julia Gaudio, Charlie K. Guan
Consider points generated uniformly at random in the unit square, and let be the length of their optimal traveling salesman tour. Beardwood, Halton, and Hammersley (1959)…
One-at-a-time knockoffs: controlled false discovery rate with higher power
Charlie K. Guan, Zhimei Ren, Daniel W. Apley
We propose one-at-a-time knockoffs (OATK), a new methodology for detecting important explanatory variables in linear regression models while controlling the false discovery rate (F…
Sharp exact recovery threshold for two-community Euclidean random graphs
Julia Gaudio, Charlie K. Guan
This paper considers the problem of label recovery in random graphs and matrices. Motivated by transitive behavior in real-world networks (i.e., ``the friend of my friend is my fri…
Exact Label Recovery in Euclidean Random Graphs
Julia Gaudio, Charlie Guan, Xiaochun Niu +1
In this paper, we propose a family of label recovery problems on weighted Euclidean random graphs. The vertices of a graph are embedded in according to a Poisson poi…
